| 摘 要： | 本文提出一种对测量仪表和控制器误动作等引起的大扰动或异常值有较好鲁棒性的离散自适应控制策略,并讨论了基于文献6]的鲁棒辨识算法的自适应控制算法,对确定性线性系统中的稳定性和跟踪最优性、递推参数估计的收敛性和一致性的两定理进行了证明。计算机仿真表明,本文控制算法对大扰动或异常值具有良好的鲁棒性和最优跟踪特性。

| Abstract: | This paper presents a novel robust discrete adaptive control method for a class of great distur- bances or outliers generated by faults of measuring instruments,misoperations of controller,and so on. The robust adaptive control algorithms based on the robust identification algorithm in paper6]is dis- cussed in detail.For deterministic linear systems,two theorems about its stablity and tracking optimal property,and the convergence and consistence of the recursive parameter estimates are stated and proved strictly.A computer simulation example for linear systems shows us the good robustness for the great disturbances or outliers and the tracking optimal property of the adaptive control method proposed in this paper. |
