SMC AS speed control, AS FLOW CONTROL - SMC

This means that it can achieve a high level of precision in controlling the system. Low sensitivity: SMC is insensitive to modeling errors and uncertainties in the system. This makes it a suitable technique for controlling systems with significant uncertainties or disturbances. Simple implementation: SMC can be implemented easily and with a relatively simple design, making it a practical choice for many applications. Energy efficiency: SMC can reduce energy consumption by minimizing overshoots and improving the transient response of the system.Chattering: One of the most significant drawbacks of SMC is the possibility of chattering, which is a high-frequency oscillation that can occur around the sliding surface. Chattering can cause excessive wear and tear on the system and can be audible, making it unsuitable for certain applications. High control effort: SMC can require a high control effort, which can lead to increased energy consumption and wear on the system components. Dependence on model accuracy: SMC is dependent on an accurate model of the system, and any modeling errors can lead to poor performance or instability. This means that modeling and identification are critical for the success of SMC. Parameter tuning: The design of the sliding mode controller requires the selection of appropriate control parameters, which can be challenging and time-consuming. Additionally, the parameters may need to be adjusted based on changes in the system or operating conditions. Implementation complexity: SMC requires the implementation of a sliding mode motion, which can be more complex than other control techniques. This can require additional

Hi Sandy, Thanks for dropping me the mail. I've sent you a reply. Now back to this post, I believe there is still some confusion...1. Excerpt from the 'Sophos Mobile Control Administrator Guide' (Product version: 4, May 2014), Section 12.1, "Available compliance settings", page 30:SMC app Synchronization gap: Specify the maximum interval between iOS app synchronisation processes for devices. For further information, refer to the Sophos Mobile Control user guide for Apple iOS.Note: This setting only applies to devices with an iOS version below iOS 7. It has no effect on iOS 7 devices.2. Except from Sophos KB article 120888 'Requirements for the Sophos Mobile Control iOS app to support automatic sync and locate':Note: This article only applies to devices running iOS 7.1 or higher. Former iOS versions did not support the automatic background synchronization correctly3. SMC App sync DEFECT:From my knowledge and communication with Sophos support, the background refresh should work on iOS 7 devices, however there is a confirmed defect with the current version of SMC (4.0.0.4) in that the messages are being sent from the SMC iOS app back to the SMC server, but they are not being processed correctly by the SMC server.As a result, the phones become non-compliant because they don't appear to have contacted the SMC server within the timescale set in the compliance settings. I have been requested by Sophos to disable the compliance setting "SMC app Synchronization gap" until a fix is supplied, apparently "within a a few days"...NB: This maybe specfic to my set-up, so if you think you have the same problem, I suggest you raise a support case with Sophos technical support.4. Except from Sophos feature pages 'Ability to Force Sync of iOS SMC app'...With SMC 3.6 and iOS7, we can trigger the app to sync data back to the server. This works in all cases, the app is running in the background. If the app is completely stopped, it does not work. This is a limitation of the iOS platform.NB: In SMC v4, this is performed by a 'Refresh data' action.Regards, JohnP.S. If you want a better understanding of the sync mechanism, my understanding is that the Sophos Mobile Control server tries to send out an APNS trigger once a day so the iOS Sophos Mobile Control app (which must be either active or running in the background) will synchronize. Here's a must read on APNS for techies

Be best to force quit them all, before shutting down your Mac. To do so, simply press Command + Option + Esc. Then click the Apple Menu > Shutdown. This way, there’s a solid chance the apps causing the trouble will stabilize and stop leading your Mac to shutdown unexpectedly.Reset Your Mac’s SMC SettingsIf the issue continues to happen after doing the previous troubleshooting step, the next thing that you can try doing is resetting your Mac’s SMC (System Management Controller) setting. You’ve heard about SMC before right? If not, well, it’s a small chip inside your Mac that is responsible for controlling almost all the vital functions of your Mac. These include the battery, fan, power, and others. If any of these components malfunction and cause your Mac to keep turning off, resetting the SMC should normally fix the problem.The process of resetting the SMC depends on whether you are using an Apple Silicon Mac or Intel-based Mac. Follow the steps below to reset the SMC Settings.For an Apple Silicon Mac, if your Mac is not plugged into power when it keeps on shutting down, try plugging it into a power outlet and then restart it to properly reset the SMC settings.For an Intel-based Mac, shut down your machine, then press and hold Control + Option + Shift keys for 7 seconds and the power button. Release the keys after another 7 seconds, then press the power button again to reset your Mac’s SMC settings.Reboot Your Mac to Safe Mode to Isolate the ProblemMost troubleshooting tips on Macs that keep turning off would recommend reinstalling macOS right away if the problem continues after doing the previous tips above. But before you do that, I would recommend isolating the problem first. You can do this by rebooting your Mac into Safe Mode. Similar to resetting your Mac’s SMC, the process will slightly differ depending on what Mac model you are using. See the steps below to boot your Mac into Safe Mode.Reboot Your Applie Silicon Mac into Safe Mode.Shut down your Mac.Turn on your Mac and continue to press and hold the power button until you see the startup options window.Select your startup disk, then press and hold the Shift key while clicking Continue in Safe Mode.Log into your Mac. You might be asked to log in again.Reboot Intel-based Mac into Safe Mode.Turn on or restart your Mac, then immediately. SMC-control Follow. Overview Repositories 1 Projects 0 Packages 0 Stars 0.

Variations in the coal quality and maintain optimal gasification conditions. The controller can be designed to be robust to uncertainties such as changes in the coal seam composition, temperature, and pressure, as well as other external factors such as air or water ingress. A robust model-based control algorithm can help to improve the efficiency and productivity of UCG operations by maintaining optimal gasification conditions and improving the quality of the gas product. It can also help to reduce the environmental impact of UCG by minimizing waste and emissions. However, developing an accurate model of the UCG process can be challenging due to the complex physics involved in the process, making model validation and calibration critical for the success of the control system.In UCG, the sliding mode control (SMC) application was the most highly researched type of robust control with a model. Model-based sliding mode control (SMC) has excellent potential to be applied in UCG processes. The designed SMC control with a 1-D packed bed model of UCG brought perfect results in stabilizing the calorific value of syngas. In general, sliding mode control is a control method that can address these challenges by creating a robust control system that is insensitive to uncertainties and disturbances. It does this by creating a sliding surface that the system trajectory is forced to converge to, which can improve the stability and robustness of the system. In the context of UCG, model-based SMC can be used to control critical process variables such as temperature, pressure,

And airflow rate to maintain optimal gasification conditions and to improve the quality of the gas product. However, developing an accurate model of the UCG process can be challenging due to the complex physics involved in the process, making model validation and calibration critical for the success of the control system. In addition, some system states are immeasurable and must be estimated by a state estimator (e.g., a Kalman filter or an Utkin observer). The controller can be designed to be robust to uncertainties such as changes in the coal seam composition, temperature, and pressure, as well as other external factors such as air or water ingress. SMC can handle uncertainties and disturbances in the gasification process, providing robust and accurate control of gasification agents’ flow rates. Pressure control is another critical parameter in UCG, and SMC can be used to control the pressure in the system. SMC can control the temperature of the gasification reaction and provide a fast response and high accuracy, minimizing temperature fluctuations and ensuring that the process operates at the desired temperature. Overall, sliding mode control is a powerful technique. Its robustness, fast response, and high accuracy make it particularly useful for controlling complex and uncertain systems such as UCG. As a result, the advantages of SMC often outweigh the disadvantages, and it remains a popular choice for controlling complex and uncertain systems.Overall, model-based robust control can provide a powerful and flexible control strategy that can improve the performance, stability, and efficiency of UCG operations.

Of steps.Resetting SMC on MacBook Pro / Air (2018 and later) – Part 2Go to the  Apple menu and choose “Shut Down” to turn off the MacAfter the Mac is turned off, press and hold the right SHIFT key, and the left OPTION key, and the left CONTROL key, for 7 secondsWhile still holding those keys, now press and hold the POWER button for 7 more secondsRelease all of the buttons and keys, then wait a few more secondsNow press the Power button again to turn the Mac onWhatever the issue with the System Management Controller was should now be resolved, assuming the problem was with the SMC in the first place anyway. If after resetting the SMC the MacBook Pro or MacBook Air continues to experience problems, then perhaps the SMC reset failed in which you can simply try the process again, or the problem may not be related to the SMC, or the issue may not be resolvable by a simple SMC reset. Remember that SMC related issues are almost always related to hardware issues, like blasting runaway fans, or backlit keyboards not working, or USB-C ports not properly charging the Mac, things of that nature, and SMC related difficulties pretty much never pertain to software or system software. Another common troubleshooting trick for managing other curious related issues is to reset the Mac PRAM / NVRAM, a process which is the same on all modern Mac models.Problems with system software are sometimes resolved by restoring from a prior backup, or by reinstalling MacOS itself, and problems with software is often resolved by updating the software, or deleting it and reinstalling it, or trashing related preferences. It’s important to note that the above method of resetting the SMC pertains only to T2 equipped portable Macs with Intel chips, like MacBook Air and MacBook Pro from 2018 onward, and not with any other Mac, nor any Apple Silicon (M1, M2, M4, etc), or older Mac model. If you have a different Mac, then you can learn how to reset those other Mac models SMC here.

The system, model-based ESC can provide insights into the underlying dynamics and behaviors of the system, which can inform future design and optimization efforts.Model uncertainty: The accuracy of the optimization results in model-based ESC depends on the accuracy of the mathematical model of the system, which may not always be completely accurate. Model uncertainty can lead to suboptimal performance or even instability in the control system. Model complexity: Developing a mathematical model of the system can be a complex task, particularly for systems with highly nonlinear and dynamic behaviors. Model complexity can lead to increased computational requirements and increased design effort. Model validation: The accuracy of the model used for optimization must be validated through experimentation or other means. Model validation can be time-consuming and costly. Model mismatch: Even with accurate models, there may be discrepancies between the model and the system’s actual behavior, which can lead to suboptimal performance. Implementation challenges: Implementing model-based ESC may require specialized hardware or software, leading to increased costs or design effort.[25,33,83]Sliding mode control (SMC)Robustness: SMC is a robust control technique that can handle uncertainties and disturbances in the system. This means that it can maintain control even when there are changes in the system or external factors affecting the process. Fast response: SMC has a fast response time due to the sliding mode motion, which allows it to track reference signals quickly and accurately. High accuracy: SMC has high accuracy because it eliminates the steady-state error that is common in other control techniques.
