摘　　要：通过求解Riccati型方程可以设计一个状态反馈控制器,可以使MIMO系统对某些故障具有一定的容错性能。针对系统的传感器故障,采用遗传算法对求解Riccati型方程时所用到的初始矩阵进行全局优化,得到系统的最佳反馈阵。对某型导弹的简化模型进行仿真试验,结果证明上述方法的有效性。对于执行器故障情形,也可以采取类似方法。To make MIMO system fault tolerant, a feedback control system can be designed by solving the Riccati Equation. Considering the sensor failure of the system, genetic algorithm is used for optimizing the initial matrix used for solving the Riccati Equation, and an optimal feedback matrix is obtained. Simulated test was carried out for a simple model of a certain type of missile, and the result proved the effectiveness of the method. Similar method can be used for processing the failure of actuator.
