Dear friends, can I ask how is the pid constants calculated? Ty

The PID proportional proportional is simple it is just a differential using error. if you make a change in the input you get an immediate change in the output PTerm is added to the output. if proportional is 1 and the input changes by 10 our output changes by 10. proportional is a floating poin…

What is not mentioned in that video is how the input and output values relate to the K values. It would be more useful if the program code was available for study. You may (or may not) be interested in this Thread which explored the subject. ...R

Robin2: I would like to study this further because it is a worked example for the control of an electric motor, and is also a system that requires a quck response - unlike (say) a heating system. However when I looked more closely I realized that the code you have posted is only for your PID capa…

Thanks for that. Much appreciated. I will take a bit of time to try to understand it. At the moment I don't have any plans to build a copy. (I have no interest in football myself :slight_smile: ) Am I correct to assume that #include "MPU6050_6Axis_MotionApps20.h" refers to a standard library rather…

They are not calculated. They are experimentally determined.
