开关磁阻电机调速系统的积分饱和现象导致了系统的控制性能较差,针对这一问题,提出了变比例退饱和式PI调节器设计方法,并给出了调节器参数整定方法。此外,分别在恒速空载和变速带载情况下,利用MATLAB/Simulink软件验证了传统PI调节器、抗饱和式PI调节器和变比例退饱和式PI调节器的控制性能。结果表明:变比例退饱和式PI调节器具有更好的动态性能和抗扰性能。

[Abstract]
In order to solve the integral saturation problem in speed regulating system of switched reluctance motor (SRM), which leads to the poor control performance, a design method of variableproportiondesaturation PI regulator is proposed, and its related parameter setting method is given. By utilizing the MATLAB/Simulink tool, the PI regulator performance of the traditional method, the antisaturation method and the variableproportiondesaturation method are verified under the conditions of constant speed with noload and variable speed with load, respectively. The results indicate that the variableproportiondesaturation PI regulator has better dynamic performance and antidisturbance performance.
