为改善开关磁阻电机（简称SRM ）的非线性特性问题，提高开关磁阻电机调速系统（简称SRD ）的响应特性和稳定性，对 SRD 采用双闭环控制，即速度外环和电流内环。其中速度外环采用模糊 PI 控制技术，借助 MATLAB/SIMULNK对系统进行建模和仿真。将其仿真结果与常规PI仿真结果进行分析比较。结果表明基于模糊PI控制的开关磁阻电机调速系统，响应速度提高了40%，超调量减小1.2%，调节精度和稳定性都大大提高，系统震荡也明显减小。

In order to improve the switched reluctance motor (SRM) problem of nonlinear characteristics, improving the switched reluctance motor drive system (SRD) response characteristics and stability.Using dual closed loop control on SRD , namely the speed of the outer ring and inner current loop.The speed of the outer ring use Fuzzy PI control technology , then under MATLAB/SIMULNK environment, building SRD model to simulation. The results with the conventional PI simulation results were analyzed and compared.The results show that the switch reluctance motor drive system based on fuzzy PI control , response speed improved by 40%,the overshoot is reduced by 1.2%,regulation accuracy and stability are improved obviously ,system shock is also significantly reduced.
