Re: Problems Using PID for Velocity

We are using the PID code as it was originally provided. As the velocity approaches the target value, the error approaches zero and the corresponding pwm value will also go to zero. This seems to hold the velocity at about half of the commanded value, which makes sense. Have other teams had this problem and how have you gotten around it? Also in the tuning example from Joel J., what do you do with DIV_V?
