An adaptive non-linear observer-based controller is designed for a full model of an induction motor including both electrical and mechanical dynamics. The controller is designed primarily for speed control and is then modi"ed to address position control. Without #ux measurement, the controller has t

The problem of' controlling a class of induction motors using a digital scheme is considered. An observer-based controller is designed to estimate the rotor currents and to decouple the ,fidl model into a rotor subsystem and a stator subsystem. An optimal state ,feedback control is then developed to
The induction motor has very good qualities\*reliability, ruggedness, relatively low cost, etc., for industrial applications. The reason for this is that there is no mechanical commutation: the rotor consists simply of closed windings in which currents are induced by a rotating magnetic "eld set up
An output feedback control for induction motors which is based on rotor speed and stator current measurements is presented. It is adaptive with respect to constant unknown torque load and rotor resistance. The main feature of this control is the incorporation of a novel adaptive flux observer which
