Abstract:
A system and method of implementing servomechanism control without rate feedback is provided. A position feedback signal is filtered using a non-linear lead-lag filter that has a variable frequency response to thereby generate a compensated position feedback signal. A position error signal is generated from a position command signal and a sensed position signal, and the frequency response of the non-linear lead-lag filter is varied in response to the position error signal. A compensated position error signal is generated from the commanded position signal and the compensated position feedback signal. The compensated position error signal is at least selectively filtered using a non-linear integral filter that has a variable gain to thereby at least selectively supply a filtered position error signal. The gain of the non-linear integral filter is varied in response to the compensated position error signal.
