Robust Speed Control of Switched Reluctance Motor Drive Based on Full Order Terminal Sliding Mode Control

This paper presents a new speed control method for Switched Reluctance Motors (SRMs) based on Full Order Terminal Sliding Mode Control (FOTSMC). The proposed solution satisfies finite time convergence with external load disturbances, and guarantees the tracking error stability by using Lyapunov method. The method is applied on the 3-phase SRM at middle and nominal speeds using MATLAB/SIMULINK. To verify the benefits of the presented technique, the controller response is compared to the classic PI controller and the standard Sliding Mode Control (SMC) at no-load and full load operating conditions. Simulation results confirm that the presented method has higher degree of robustness against load torque.
