Great video! I wasn't 100% sure what you meant by an integrator-like plant, despite the example of a motor. Is that idea that a motor, given a constant signal, over time accumulates distance in whatever it's driving? It's not clear to me how that would obviate the need for an integral factor in the controller.
@ehsanu16 жыл бұрын
Oh, and can you point to any resources to help with the "understand the system you're controlling" bit?
@BrianBDouglas6 жыл бұрын
That was confusing, wasn't it? A motor in position control acts like an integrator for the reason you state - it accumulates distance given a constant signal. The motor control example I used was a velocity controller, which doesn't act like an integrator since a constant voltage produces a constant velocity. Therefore, my statement about the motor controller was misleading. To understand why an integrating transfer function may not require an integrator in the PID controller, search Google for "transfer function type steady state error" and click on the UMich link at the top. There is a great explanation of transfer function type and how that relates to steady state error. If you want zero steady state error for a step input then your system needs to be a type 1 (or one pole at the origin, or another way of putting it - an integrator). If your plant doesn't have that integrator, then you'll need to add one in the controller. Hope this helps.

I once worked in a Florida based company that manufactres security products and I implemented an algorithm (C and Assembly code) in the microcontroller that perfoms "Automatic-Self-Testing" for the product to save time testing the product after production, this also saved time and money on testing the product. The reason I metioned this is that now I am thinking of similar automatic-self-tuning algorithm that will drive the Drone to the desired behaviour and automatically adjust the PID gains over time to compensate for the aging and deformation of Dron parts and sensors. I think this kind of algorithm will solve the tuning problem of PID control loop. Has anyone done anything like that before? I guess such algorith may need a high MIPS ARM microcontroller with very generous memory. Once this is a success I will add it to the service of my small business.

Hello Brian, your videos are fantastic! A perfect tie-in for this Part4 PID Tuning would be Benjamin Vedder's VESC Tool, specifically, the PID Controller menu tab (the default numbers are meant to be tweaked for different motors, but there is no clear guide as to how). If you could integrate Benji's VESC Tool PID Controllers into your Part 4 PID Tuning video (as a new video), it would be of tremendous, immediate benefit to thousands of e-bike, e-skateboard and quadcopter users. Thank you!

Hi Brian. Thanks a lot for sharing your knowledge with us. I am working on a microgrid simulink model where voltage error is at the input of the PI controller. What result should I expect at the output of the controller? Do I need to get the value of the reference voltage by tuning the controller? Also can Ziegler Nichols method be used for all the cases?

I draw everything in Photoshop with a black background using a Wacom tablet. I record the screen while I do the drawing using Capto (but any screen capture program will work). Then I take that video into Final Cut Pro to speed it up and cut out any mistakes I made. Finally, I record the voiceover in Final Cut and publish the video.
