| 摘 要： | 针对一类非线性系统的执行器增益故障,在考虑控制输入幅值约束下,研究了故障系统的主动容错控制策略。利用静态输出反馈控制策略,基于Lyapunov理论和线性矩阵不等式技术给出了重构容错控制器的递推设计方法,确保故障闭环系统在满足给定控制输入幅值约束下的鲁棒稳定性,并具有与无故障正常系统接近的其他优化控制性能。仿真算例表明了本文容错设计策略的有效性。

| Abstract: | The active fault tolerant control is investigated for a class of nonlinear systems with actuator faults and magnitude constraint in the control input.The abrupt faults in the gain matrix of actuators are modeled to be the constant type.Based on the Lyapunov theory and linear matrix inequality technique,the iterative design method for reconfigurable fault tolerant controller is proposed by using static output feedback strategy,such that the corresponding closed-loop system is robust stable with the given mag... |
