摘要
针对系统的不确定性和扰动满足匹配条件 ,不确定性界和扰动界未知的情形 ,讨论含时变不确定性线性系统的鲁棒跟踪问题。自适应控制器的设计不涉及不确定性界和扰动界 ,运用变结构方法 ,可使带扰系统实现渐近跟踪。该方法适合一类较广泛的不确定系统 ,鲁棒性较强。仿真例子表明了该方法的有效性。
The problem of robust tracking control for a class of linear systems with time varying uncertainties and disturbance is studied. The uncertainties and disturbance are bounded by unknown bounds, which are not need to be considered in the proposed adaptive controller design. When certain matching conditions are satisfied, the system with disturbance may track asymptotically the known object by the variable structure way. Compared with existing results, the proposed method is more effective and enhances the robustness of controllers. The simulation demonstrates the effect of this method.
