I have a questions about using PID regulator functions from arm_math.h library.
In that lib there are 3 different types of handling PID regulator:
My questions are:
- In which case to use which regulator?
- My case is: I need to use PID regulator to control current generated from PWM signal by regulate Duty Cycle of that PWM. Which of those 3 PID types is the best for that implementation?
