Sliding mode control of switched reluctance motor drive

The principles of the sliding mode control for Switched Reluctance motor drive were presented. The mathematical models of the sliding mode control for the drive were described. The control pattern, such the input parameters and output parameter, the setting of the turn-on angle and the turn-off angle of the main switches, the measure of the feedback signal of the practical rotor speed, the function of the output switch signal of the sliding mode controller, were given. The hardware components of the developed prototype system were introduced, such as the four-phase 816 structure Switched Reluctance motor with eight stator poles and six rotor poles, the four-phase asymmetric bridge power converter, the controller based on the Intel80C196KB CPU circuit board and the keyboard & display circuit board. The photographs of the hardware were shown. The experimental tests of the developed prototype were made, while the DC supplied voltage was 110 V The tested rotor speed curves were also presented. It is shown that the Switched Reluctance motor drive with the sliding mode control have the advantage in robustious.
