Abstract

This paper deals with the design of a nonlinear observer for sensorless induction motor control. Based upon the circle
criterion approach, a nonlinear observer is designed to estimate pertinent but unmeasurable state variables of the considered induction
machine for sensorless control purpose. The observer gain matrices are computed as a solution of linear matrix inequalities (LMI) that
ensure the stability conditions of the state observer error dynamics in the sense of Lyapunov concepts. Measured and estimated state
variables can be exploited to perform a state feedback control of the machine system. The simulation results are presented to illustrate
the e®ectiveness of the proposed approach for nonlinear observer design.
