Synchronization of Synchronous Reluctance Motors Using the Discrete Sliding Mode Control Technique

Abstract EN

The synchronous reluctance motor (SynRM) drive system is known to exhibit chaotic behavior under specified conditions.

In this paper, the discrete-time sliding mode control (DSMC) technique is used to synchronize two SynRMs starting from different sets of initial conditions.

The mixed variable speed reaching law is adopted in the design of the controller scheme.

The parameters of the designed control scheme are tuned using a genetic algorithm (GA).

Simulation results are presented to demonstrate the effectiveness of the proposed controller.

In addition, the performance of the proposed control scheme is studied through simulations when bounded disturbances and mismatches between the parameters of the systems and those of the control scheme exist.

The simulation results show that the designed control scheme is robust to bounded external disturbances and to mismatches in the parameters of the systems.
