摘要
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。
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 variable-proportion-desaturation 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 anti-saturation method and the variable-proportion-desaturation method are verified under the conditions of constant speed with no-load and variable speed with load,respectively.The results indicate that the variable-proportion-desaturation PI regulator has better dynamic performance and anti-disturbance performance.
