摘要: 研究一类不确定性时滞系统的鲁棒镇定问题.当系统既有状态时滞又有控制输入时 滞,而且系统的状态和控制输入均含有不确定性时,假设不确定性满足具有一定物理意义的 匹配条件,得到了系统可由基于观测器的状态反馈鲁棒镇定的充分条件,并给出了观测器和 反馈控制器的设计步骤.该方法仅需求解两个黎卡提不等式.Abstract: The problem of robust stabilization for a class of uncertain delayed systems is addressed. The considered system has uncertainties and delays in both state and control input. The uncertainties are assumed to satisfy the matching condition in some physical sense. A sufficient condition is obtained that the uncertain delayed system is robust stabilizable via observer-based state feedback controllers. And the main steps of designing the observer and feeback controller are presented. One only need to solve two Riccati inequalities when using the proposed method.
