On a sliding mode control and observer of induction motor

The aim of this paper is to develop a general class of manifolds on which sliding mode flux observation and control of induction motors. For flux-speed tracking, we consider the case where the sliding surface is formed by the derivative of the output tracking error and a function of this error. For flux observation, the surface is a function of the estimated error. Simulations results are given to highlight the performances of the proposed control method.
