PID Controller for Servo Motor explained: How does it work?

[@ivolol]

Thanks very much, the explanation of how the parts of the circuits worked and when they worked at different frequencies is nicely explained. I guess the fun time is always finding the good concrete values for any particular example :D

You're welcome. Thanks for watching and your comment. Glad that you like this video and it is useful. Well said 😄 yes, the fun challenge is the right component selection to keep PID controller stable and functional with proper response time for a given application. Alright, I'll prepare another PID example sometime soon discussing controller coefficients and practical choices for components. I will also prepare an example/tutorial for PLL as a related topic since this circuit is effectively a Speed-Locked Loop (SLL). Thanks again.

@@STEMprof you are very generous, thanks for your videos. I find most of the time even though they have the math applied, it's just enough that relates to the problem and is easy to see how it works, but yet still working from first principles. Other places either skip it entirely, are very surface level, or dive straight into deep theory so you'd need a book with examples to help you understand as well.

@@ivolol My pleasure, And thank you for watching and your kind words. I appreciate. I am glad that you like my circuit videos and you find them useful and practical. Thank you very much. 🙏🙋‍♂️

This is a little new to me. So far I have dealt with PID Mass Flow Controllers, temperature controllers, and PLLs. As I understood the reason for using PID for temperature control was to prevent overshooting and undershooting and ensure the fastest possible correction. So the same principles would be applied here to the rotational speed of a motor? As far as PLLs are concerned, I am and always been fascinated by them. I think they are absolutely marvelous pieces of electronic technology. Maybe worth talking about? Also, some discussion of the practicality of adjusting these coefficients in the PID controller would be very interesting. Anyway, thank you very much for this post. I didn't know how I would go about putting together that kind of controller before I watched your post.

Thanks for watching and sharing your thoughts. Glad that you liked this video and it is helpful. You are right, the same principles as PLL and as PID for thermal control are applied in this example. Sure, hopefully soon I'll prepare another PID example discussing controller coefficients and practical choices for components. I will also prepare an example/tutorial for PLLs. Thanks again.

This is the first time I ever see a PID with actual components instead of just math that makes my head hurt. 😄

Thanks for nice explanation and the right amount of formulas. One thing I'm missing. I was really expecting to get some final formula based on R, C used in schematic, as a sum of 3 separated parts (proportional, integral, differential) as in basic formula. Basically to see the K parameters, which resistors and capacitors are influencing it.

Thanks for watching, your comment and good points. Glad that you like this video. Alright, I'll prepare a follow-up PID controller circuit example and video sometime soon discussing practical choices for components and controller coefficients. Thanks again.
