| 摘 要： | 对含有有界扰动和参数不确定性的离散时间被控对象建立多个辨识模型, 覆盖被控对象的参数不确定性. 给定指标切换函数, 构成多模型自适应控制器. 引入“局部化”技术, 在保持计算精度的同时, 提高了计算速度. 同时证明, 多模型自适应控制可以保证闭环系统输入输出稳定, 且保证对给定有界参考输入、被控对象输出可在一给定界范围内跟踪参考输入.

| Abstract: | Multiple models were set up to cover the parameter uncertainty of a discrete time system with bounded disturbance and uncertain parameters. And the multi-model adaptive control was formed by using a given switching index function. The "localization" method was used to speed up the computation of multi-model adaptive control, and the accuracy was not lost. It was proved the closed-loop system is input and output stable (BIBO), and the output of system could track any bounded reference input with bounded error. |
