- Abstract
In this paper, a composite sliding mode control-observer approach is presented for the induction motor drive. This approach, based on the singular perturbation theory, decomposes the original system into separate slow and fast subsystems and permits that separate slow and fast control and observer can be designed for each subsystem and then combined into a composite control and observer for the original system. The controller design uses the sliding mode technique and is divided in two phases: slow control and fast control so that a final composite control is obtained. In addition and assuming that only the fast states are available; a two time scale sliding mode observer design is proposed for which a stability analysis is easily made. The simulations results validate the performance of the proposed approach.
