摘　　要：推导了广义预测控制系统的内模控制结构,据此分析闭环系统稳态特性,从结构上阐明由模型失配所带来的鲁棒稳定性问题的实质.分析了噪声滤波器设计对闭环系统鲁棒性界的影响,依据小增益原理给出了频域中闭环系统鲁棒稳定的条件,通过仿真实例说明了适当的选取噪声滤波器能改善系统的鲁棒性,提高了系统的鲁棒性.In this paper the internal model control structure of general predictive control is derived and an analysis on the closed - loop properties of general predictive control is made. The internal model control structure shows the nature of robustness. The robust stability condition of the structure uncertain system is studied based on the minimum gain theory. In the end an example is given and the stability bound with various of the filter or observer is shown, the simulations showing its efficiency.
