Chaos Control of Permanent Magnet Synchronous Motor via Sliding Mode Variable Structure Scheme

A sliding mode variable structure controller for chaotic control in the permanent magnet synchronous motor (PMSM) is presented in this paper. The controller is deduced based on the Lyapunov function theory and the function switch control strategy. The angle speed of the PMSM can be flexibly adjusted according to the engineering requirement by the controller. The control method has powerful robust and is very easy to realize in engineering. Simulation results are presented to show the effectiveness and robust of the method.
