Abstract
This invention describes a reconfigured form of the PID compensator such that the rate of change of the position error is inherently limited without affecting the performance of the servo loop when the position error is small. The technique described here maintains the performance of the conventional PID compensator when the position error is close to zero, which is the operating point of primary interest.
