Abstract
This paper deals with the design of a nonlinear observer for sensorless induction motor control. It is wellknown that induction motor is one of the widely used machines in industrial applications. However, induction motor is also known as a complex nonlinear system in which time-varying parameters entail additional difficulties for the induction machine system control. Based upon the circle criterion approach a nonlinear observer is designed to estimate pertinent but unmeasurable state variables of the 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 used to improve the effectiveness of a state feedback control of the considered induction motor system. The simulation results are presented to illustrate the validity of the proposed approach for nonlinear observer design.
