Variable gain switching exact differential observer‐based compensation control for servo system with backlash

Abstract This paper proposes a novel variable gain switching exact differential observer (SEDO) to deal with the state estimation of mechanical servo system with unknown backlash. In order to compensate unknown non‐linear backlash accurately, a switching backlash torque mathematic model is construct...
