Robust decoupling controland extended sliding mode observer for an induction motor

Abstract : This paper presents a feedback linearization strategy and a robust controller to permit a decoupling and regulation of the motor states in order to assure a good dynamic performance and stability of the global system. As the control required the knowledge of the instantaneous flux of the rotor and the rotor parameter estimation can improve the control quality, a fifth-order discrete-time extended sliding mode observer is proposed for on-line estimation of rotor fluxes and rotor time constant. The simulation and experimental results for a 5.5 kW induction motor are presented to illustrate the validity and the high robustness of the proposed approach against parameter variations and disturbances.
