基于DSP的开关磁阻电机调速系统

Switched reluctance machine combines the electrical machine theories with power electronics technique and the microprocessor control technique, measurement technique .It has a lot of advantages, such as simple structure, strong structure, high efficiency, wide speed adjusting range, multivariable control. So it is used widely. Firstly, the paper introduces the theory and features of SRM, the composing of SRM drive system and research survey. SRM is a nonlinear system which is multivariable and strong coupling.And analyze the advantages and disadvantages of three control modes for SRM, then choose the best mode for this system .The paper proves that fuzzy controller has the best effect. Finally, we tested and compared the different strategies on the hardware experiment system, and got the experimental waveforms. It validates that the control strategy is correct. And the SRM drive system has a good static and dynamic performance.
