Biologically inspired sliding mode control of switched reluctance motor

As the ideal sliding motion can´t be formed in the practical system using a sliding mode control, the sliding mode controller for switched reluctance motor has the problem of large speed ripples. In this paper, a biologically inspired shunting model is incorporated into the variable structure sliding mode control for a switched reluctance motor in order to improve its performance. The simulation by MATLAB demonstrates the effectiveness of the proposed control scheme. The simulation results show that the switched reluctance motor using the proposed biologically inspired sliding mode control has the better speed tracking performance than using the conventional sliding mode control. In addition, the switched reluctance motor controller keeps the features of parameter insensitivity and rapid recovery from load disturbances.
