Switched Reluctance Motor Control Simulation Based on VSS

Torque tipple and non-liner model are the major disadvantages of aswitched reluctance motor (SRM). Based on the theory of Variable-Structure control with Sliding mode, a general design of sliding mode con-troller is pplied to the control system of SRM. Without knowing the precise model of motor the design of controller is realized and the process of design is also simplified, which makes use of its rapidity and fully self-adaptability. It is shown through the computer simulation experiments that , comparing with tradition control, the VSS improves system dynamic performance and robustness, and reduces motor torque tipple effectively.
