Adaptive control of power electronic drives for servomechanical systems

This paper presents adaptive-control schemes that estimate load-model param eters and adaptively "tune" a digital controller for an inductively-coupled power delivery circuit. Estimation algorithms,are presented that utilize s pecific recursive formulations, which provide adequate noise immunity in a power-electronic environment. The techniques are demonstrated using a servo mechanical system and a 1.5-kW prototype power electronic drive.
