Description

To compensate the margin of the system stability in the high frequency, the conventional PI velocity controller is extended by PID controller.

GVD is a tuning variable of the PID velocity controller, which sets the gain of the derivative feedback of the actual velocity. The other related parameter is the filter time constant GVDT.
