Fuzzy control and it’s application in switched reluctance motor control

对常规的模糊控制器的设计进行了分析研究。以提高系统精度为目的,简单实用为原则,设计了模糊PID控制器。仿真结果表明,所设计的模糊PID控制器大大提高了系统的控制精度,加快了系统的响应特性,可以做到理论上无静差,明显优于常规的模糊控制器。最后把设计的模糊PID控制器应用到开关磁阻电动机调速系统中,经过反复实际调整,确定了一组合适的量化因子的数值,这对量化因子使用理论值来说是个突破。同时实验结果表明,文中设计模糊PID控制算法不但可行,且效果很好,已在实际中得到成功的应用。

This article firstly analyzed and studied the design of general fuzzy controller。 Take raising the system accuracy as the purpose, simple practical as a principle and designed the fuzzy controller of PID。Simulation results express that the fuzzy controller designed in this article raised the control accuracy of the system consumedly and speeded the system responds to the characteristic, can attain to have no static error theoretically and obviously better than typical fuzzy controller。In the end, applied the designed fuzzy controller of PID to the SR motor' s speed regulation system。After again and again actually adjustments, made sure the num-ber of the appropriate quantification factors, which is a break for quantification factor usage theories value。At the same time, experi-ment results expressed that the fuzzy controll algorithm of PID designed in this article not only can be carried out, but effective and get the successful application in actually。
