Sliding Mode Control of Switched Reluctance Motor with High Torque in Low Speed

Abstract:

This paper analysis the problem of a switched reluctance motor (SRM), which is based on the phase currents by using three independent current sensors. In addition, the reaching condition and stability conditions of sliding mode control (SMC) method has been discussed, and it has been applied to SRM speed control loop that compensates the torque ripple on the torque output. The proposed sliding mode controller performs better than the traditional PI controllers and is also more effectively to the external disturbances. For the switched reluctance motor, one of the factors of the torque ripple is mutual inductances, so the mathematical model of the SRM should consider its influence. And, the mechanical sensor has been used to sense the rotor position. The simulation experiment results of the control scheme using Matlab show that the proposed method for the switched reluctance motor is effective.
