凸多面体不确定时滞系统的鲁棒广义H2控制

利用变量分离方法得出闭环时滞系统具有指定广义H2性能的一个等价条件，再根据该等价条件，给出凸多面体不确定时滞系统存在鲁棒L2-L∞。状态反馈控制器的一个充分条件及控制器的设计方法，并用算例验证该方法能够求出凸多面体不确定时滞系统的最优扰动衰减水平，具有较小保守性．

Robust Generalized H2 Control for Time-delay System with Polytopic Uncertainties

An equivalent condition of the closed-loop time-delay system satisfying the generalized H2 performance was derived by using the method of variant separation. Based on the equivalent condition, a suffcient condition for the existence and design method of the generalized H2 controller were given for the time-delay system with polytopic uncertainties. An illustrative example shows the minimum disturbance attenuation level with less conservative can be calculated by this method.
