针对时滞系统的一般化内模控制方法

A GIMC Architecture for Time-delay Systems

为了克服传统反馈控制中标称性能和鲁棒性能之间的矛盾,Zhou提出一般化内模控制方法(Generalized internalmodel control,GIMC).然而在实际工业生产中,控制对象一般都含有时滞环节.本文针对含有时滞环节的真有理传递函数矩阵对象,在时滞系统既约分解的基础上,提出一种针对时滞系统的一般化内模控制方法,使得一般化内模控制方法能够应用于时滞控制对象.最后,为了验证该方法的有效性,将该控制结构应用于直流电机中,取得了良好的控制效果.

To overcome the intrinsic conflict between nominal performance and robustness in the traditional control method, a new control method called generalized internal model control （GIMC） was proposed by Zhou. However, real controlled objectives usually include time-delay. This note puts forward a GIMC method for processes with time-delay based on the doubly coprime factorization of the plant. Finally, an application to DC motor servo system is given to verify its feasibility.
