摘　　要：该文对文献 [1]所设计的输出反馈自适应控制系统进行鲁棒性分析 ;在较弱的条件下证明了该闭环系统的全局稳定性 ,还证明了输出跟踪的精度完全达到预定的要求 ,即解决了ε 跟踪问题。在仿真例子中显示出这种鲁棒自适应控制系统具有良好的跟踪性能 ,而且控制量在容许控制的范围之内。In this paper, we are analyzing the robust performance of the output-feedback adaptive control systems designed in ; Under some weak conditions, the global stability of the resulting closed-loop system is proven, and the output tracking accuracy of the adaptive control systems can be satisfied for scheduled requirement and the ε-tracking problem has been solved as well. The good track effect of the robust adaptive control systems and the range of the admissible control for used control quantities are presented in the examples of simulation.
