针对永磁同步电机调速系统，提出自调整灰色预测内模控制器。利用自调整灰色预测在线实时对转速误差进行预测，内模控制依据系统下一时刻的输出响应控制输出变量。仿真结果表明，永磁同步电机调速系统采用自调整灰色预测内模控制后在快速性、抗干扰性和鲁棒性方面都有明显提高，系统的动静态性能都优于单一使用内模控制和自调整灰色预测控制。
針對永磁同步電機調速繫統，提齣自調整灰色預測內模控製器。利用自調整灰色預測在線實時對轉速誤差進行預測，內模控製依據繫統下一時刻的輸齣響應控製輸齣變量。倣真結果錶明，永磁同步電機調速繫統採用自調整灰色預測內模控製後在快速性、抗榦擾性和魯棒性方麵都有明顯提高，繫統的動靜態性能都優于單一使用內模控製和自調整灰色預測控製。

An internal model controller of self-adjustable grey prediction is presented in conjunction with the speed regulating system of the permanent magnet synchronous motor (PMSM).Self-adjustable grey prediction realizes real-time online prediction of error of rotation speed.The internal model can control output variables based on the system output response of the next moment.Simulation results show that the performance of high speed,anti-interference and robustness of the PMSM speed regulating system is improved significantly if the internal model control of self-adjustable grey prediction is adopted,and the dynamic and static performance of the system are superior to that of a system that adopts either internal model control or self-adjustable grey prediction.
