降阶多变量状态空间自校正控制器的鲁棒性

Robustness of Reduced -Order Multivariable State-Space Self-Tuning Controller

本文建立了降阶极点配置状态空间自校正控制器的鲁棒性定量分析．在这个多变量自适应控制系统中，控制器设计中所用模型的阶低于实际过程的阶．稳定性分析结果表明，当建模误差满足一定条件时，在降阶控制器作用下的自适应闭环系统是输入输出有界的．

In this paper, we present a quantitative analysis of the robustness of a reduced -order pole-assignment state-space self-tuning controller for a multivariable adaptive control system whose order of the real process is higher than that of the model used in the controller disign.The result of stability analysis shows that, under a specific bounded modelling error,the adaptively controlled closedloop real system via the reduced -order state-space self-tuner is BIBO stable in the presence of unmodelled dynamics.
