In this paper, a nonlinear indirect adaptive sensorless speed and #ux tracking controller for induction motors is proposed. In the controller, only the stator currents are assumed to be measurable. Flux observers and rotor speed estimator are designed to relax the need to #ux and speed measurement.

Given measurements of rotor position, rotor velocity, and stator currents, we design an adaptive control scheme that is free of singularities, does not require rotor #ux measurements, and provides for simultaneous asymptotic rotor position/rotor #ux tracking despite the uncertainty associated with t
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
On the basis of a novel dynamic model obtained under a special non-linear co-ordinate transform on a d}q-axis model (w.r.t. the stationary reference frame) of an induction motor, a simple but e!ective control law for speed regulation is proposed in this paper. This controller is designed using the c
## Abstract The design of two multipleβinput multipleβoutput (MIMO) controllers for induction motors, based on adaptive passivity, is presented in this paper. The controller design method is based on concepts of equivalence passivity via adaptive feedback, previously developed by the authors. Robus
