Switched reluctance motor strong simple structure, low cost, high reliability, wide speed range, so by the world countries scholars’ attention. But because of switched reluctance motor (SRM) double convex type structure make motor in turns easy to produce great torque ripple and noise. So this paper from reducing torque ripple of perspective, studied how to improve switched reluctance motor torque ripple and noise of effective control of the strategy.Combining with the ac motor direct torque control theory is a switched reluctance motor einhorn direct torque control theory, the switched reluctance motor mathematical model of switched reluctance motor is deduced direct torque control model, and by MATLAB simulation software observation of magnetic chain, to the electric current, torque changes, and prove the direct torque control method can effectively restrain torque ripple, reducing the noise.Then this paper based on the finite element analysis software Ansoft, through the 2 d static magnetic field and transient magnetic field analysis of switched reluctance motor the static torque、magnetic chain parameters and transient field magnetic chain、current、torque change curve, the data for the later switched reluctance motor control provides value. Based on TMS320F2812 again DSP as the core controller, switched reluctance motor design the periphery of the circuit, including power transformer, electric current detection module, the voltage detection module, location, and other functions of the detector auxiliary circuit.Finally, according to the switched reluctance motor direct torque control strategy based on CCS3.3 software completed switched reluctance motor software system design, and using C language to write the direct torque control program, and related procedure, for further development of switched reluctance motor laid a foundation.
