摘要
本文研究了离散大系统存在有界干扰时的分散模型参考自适应控制问题.考察了按系统的状态变量和输入-输出变量设计自适应系统的二种情况,导得了局部控制器采用“积分+δ修正”自适应律时,复合闭环系统的所有信号和跟踪误差将收敛于一有界集的充分条件.文中并给出了一个算例.
In this paper,the decentralized model reference adaptive controlof a discretelarge-scale system in the existence of bounded disturbanceis studied.According to thestate variables and the input-output variablesof the system,two cases for designingthe adaptive system are examined,and sufficient conditions are derived,under whichall the signals of a compositeclosed loop system and the tracking errors will convergeon a residual boundedset,when the“integral±6modification”adaptive law is used in alocal controller.Besides,a simple example is given at the end of the paper.
