| 摘 要： | 对基于饱和执行器的不确定线性系统的非脆弱控制进行了研究.根据Lyapunov二次稳定性原理,证明并给出了椭球为闭环系统吸引域的充分条件,然后将该条件转化为线性矩阵不等式的优化问题,并估计出了闭环系统的最大吸引域,最后得到基于最大吸引域的非脆弱控制器参数的设计方法.仿真结果表明,与不考虑非脆弱控制相比,非脆弱控制器能使系统状态更快地稳定在原点.

| Abstract: | Non-fragile control based on the uncertainty linear system of saturation actuator is studied.According to Lyapunov quadratic stability theory,a sufficient condition of ellipsoid being the domain of attraction for the closed-loop system is proved and presented.Then the condition is converted to the optimal problem of linear matrix inequities and the maximum domain of attraction for the closed-loop system is estimated.Finally,the parameter design method of non-fragile controller based on the maximum domain of... |
