Hai,
I implemented a PID algorithm for a generator speed control by adjusting engine throttle valve using a stepper motor. Here Iam measuring RPM of generator axile output rotation with hall effect sensor as a feedback.
It works fine, but in this algorithm I changed my Kp,Ki,Kd constants in different conditions. ie nearest of setpoint I changed these constants to get fine values and if there is a big difference changed to get large error value.
My question is , can i change, PID constants in running condition? Is it favourable ?
