研究线性时滞系统的状态反馈H∞ 控制器设计问题·在状态和控制同时存在时滞以及控制输出方程具有更一般形式的情况下 ,以线性矩阵不等式的形式给出了系统存在状态反馈H∞ 控制器的充分条件·当这个条件成立时 ,利用线性矩阵不等式的解可以构造状态反馈控制律 ,使得闭环系统渐近稳定 ,而且保证干扰输入对控制输出的影响降低到指定的水平·给出的方法适用于具有多状态时滞和多控制时滞的线性系统 Research on the State-feedback H∞ Controller Design Problem for Linear Systems with Time-Delay • In the presence of simultaneous state and control delays and a more general form of the control output equation, the state feedback H∞ is given in the form of linear matrix inequalities Sufficient conditions for the controller • When this condition is true, the state feedback control law can be constructed using the solution of the linear matrix inequalities such that the closed-loop system is asymptotically stable and the influence of the disturbance input on the control output is reduced to a specified level. The method is applicable to a linear system with multi-state delay and multi-control delay
