A sliding mode based model predictive control structure for permanent magnet synchronous motor

This paper presents a sliding mode based model predictive controller for permanent magnet synchronous motor(PMSM). The proposed controller consists of model predictive controller(MPC) for outer velocity control loop and sliding mode controller(SMC) for inner current control loop. The SMC is proposed to track the desired currents in finite time. The MPC is developed to obtain optimal velocity control input for minimized cost function with constraint conditions. The closed-loop stability of the proposed controller is proven by Lyapunov theorem. Finally, simulation results are attached to validate the performance of the proposed controller.
