Adaptive control of an inductive power transfer coupling for servomechanical systems

Abstract

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