摘要: 研究了一类含有参数不确定系统的观测器型鲁棒H2控制器的设计问题.基于状态 反馈和观测器设计的可分离性原理,给出了控制器存在的充分条件和系统H2性能指标的一 个上界.利用线性矩阵不等式凸优化方法还得到了使该界达到最小的观测增益.Abstract: This paper is devoted to the problem of designing robust H2 controllers for linear uncertain systems based on state observers. Exploiting the famous separation principle, sufficient conditions for the existence of controllers and an upper bound on H2 performance are obtained. Observer matrix gains which make the upper bound minimized are also derived by the methods of convex optimization based on linear matrix inequalities.
