Title Control Principle and Simulation Research of Switched Reluctance Motor
Abstract Because of simple structure, low cost, strong and durable, good robustness, wide speed range, strong fault tolerant ability, the switched reluctance motor, which has a strong competitiveness in the market, has been widely used in agriculture and industry, machinery manufacturing, defense， and other fields. But the nonlinear structure of the switched reluctance motor leads to complex control, and large torque ripple and noises. Firstly, This paper introduced the origin, the current research and the research direction of switched reluctance motor of home and abroad, and then analyzed its advantages and disadvantages. Next, the basic theory of switched reluctance motor was analyzed, which included basic principle, operation characteristics and basic control strategies. Lastly, the mathematical model of switched reluctance motor was introduced in details. For three-phase switched reluctance motor, the each module's composition and function of the speed control system were analyzed under the Matlab/Simulink simulation platform .Through setting up simulation model of switched reluctance motor speed control system, this paper verified the influence of the power supply voltage， turn-on angle and turn-off angle to the motor. Finally, to reduce the speed pulse and static differential, sectional PI regulator was used in this subject.
