摘　　要：对于具有有界扰动的模型参考控制系统,采用Narendra直接法设计思想,利用Lya punov稳定性理论研究了稳定鲁棒控制问题.作为控制器设计的理论法则,引入变结构自适应律,给出了闭环控制系统的稳定条件及稳定范围.在较弱的条件下得到了较小的残差集,从而提高了控制系统的鲁棒性.The studied problem is related on model reference control system in the presence of bounded disturbances. The stable robust control problem is studied by use of Narendra's idea of adaptive controller designdirect method and Lyapunov's stability theory. As a theory law of controller scheme, the variable structure adaptive law is introduced. The stable condition and the range of the closedloop control systems are given. A smaller residual set is obtained in the more weak conditions, and the robustness of the control system is strengthened.
