Digital second order sliding mode control for a synchronous reluctance motor

Investigating the performance of a synchronous reluctance drive speed control system using second order sliding mode control (SOSMC) is presented in this paper. In this paper based on the theory of SOSMC, a controller for vector control of synchronous reluctance motor (SRM) is first derived and the performance of the controller is verified by simulation results. The proposed SOSMC shows good robustness to the variations of mechanical load parameters which is highly desirable in most practical applications such as washing machines, mixers, compressors, etc. The performance of the method is verified experimentally.
