摘　　要：针对常规二自由度内模控制的不足,本文提出了一种三自由度内模控制方法。此方法使系统的抗扰性和鲁棒性得到明显的改善,而且该控制算法简单、参数调整方便,理论分析和仿真实验验证了它的有效性。This paper presents a three-degree-of-freedom internal model control method to overcome the shortcomings of a conventional tw-o-degree-of-freedom internal model control. The method can improve the disturbance rejection perfor mance and robustness of the system. In addition ,its control algorithm is simple and the adjustment of control parameters is quite easy.

关 键 词：内模控制 三自由度 抗扰性 鲁棒性
