Abstract :
A sliding observer for induction machines is designed by the sliding mode approach. The observation is based on measurements of stator voltages, currents, and shaft angle. The observer is equipped with a switching feedback action to cope with nonlinearities, input disturbances, and some uncertainties in machine dynamics. A linear continuous feedback is used to characterized the convergence of observation error, which is proved to be asymptotically stable
