摘要
针对传感器失效的线性连续系统 ,利用 Riccati方程、L yapunov稳定性定理和广义逆理论 ,给出具有传感器完整性控制器的设计方法。所设计的状态反馈控制器在系统正常时 ,能使闭环极点配置在指定的圆形区域内 ;在一定条件下 ,仍能使传感器故障系统具有渐近稳定性。仿真结果表明了该方法的有效性。
Based on Riccati equation, Lyapunov stability principle and the generalized inverse theory , a design method of controller for linear continuous time system with sensor failure is presented. The induced system possesses integrity against sensor failure. The designed state feedback controller places all poles of the closed loop systems within a prescribed circular region for the normal system. Under certain condition, the same control law guarantees the system′s asymptotic stability against sensor failure. A simulation example shows the effectiveness of the fault tolerant control method.
