| 摘 要： | 考虑了脉冲切换系统的鲁棒H∞控制问题.该系统的状态矩阵和控制矩阵都有不确定性和扰动.利用线性矩阵不等式(LMI)、H∞控制理论、Lyapunov函数和变量替换方法,对这类系统给出了鲁棒稳定且具有γ鲁棒性能的充分条件.然后,使用MATLAB软件设计出H∞鲁棒动态输出反馈控制器和脉冲控制矩阵.最后通过一个仿真算例验证了文中结论的有效性.

| Abstract: | The problem of robust H-infinity control is considered for impulsive switched systems with disturbances and uncertainties in both states and control matrices.By using linear matrix inequality (LMI),H-infinity control theory, Lyapunov functions and variable transformation,we derived the sufficient conditions for this type of systems to be robustly stable with robust performance.The robust H-infinity dynamic output feedback controllers and impulsive control matrix are then designed by using MATLAB software.The numerical example illustrates the efficacy of the result in this paper. |
