Abstract :
This paper presents the development of discrete-time sliding mode rotor speed and rotor flux observer applied to induction machine drives. The conditions for the discrete-time sliding hyperplane existence are discussed. The sliding hyperplane are formed by the stator currents estimation errors and by the observed rotor fluxes. Simulation and experimental results using DSP TMS320F2812 are presented aiming to verify the effectiveness of the proposed scheme.
