摘要
提出了一种基于迭代学习观测器(ILO)将故障检测和容错控制进行统一设计的方法。迭代学习观测器不仅可以用于进行状态估计和故障检测,而且可以用于获得控制输入调节项并进行故障估计。设计重构控制律的基本思想是利用估计状态和控制输入调节项来补偿故障引起的影响。文中还给出了特定假设条件下闭环重构控制系统稳定性的严格证明。理论分析和仿真研究表明,所提的方法是有效的并可保证闭环系统具有良好的重构性能．
An unified methodology for the fault detection and the fault tolerant control based on iterative learning observer（ILO） is presented. The ILO supplies state estimates and the fault detection, and control input adjustments and fault estimates. The basic idea in the design of the reconfigurable control law is to use the estimated system states and control input adjustments for compensating the fault effect. The stability of the closed-loop system is rigorously established under certain assumptions. Both the theoretical analysis and the simulation reveal that the approach is effective and the closed-loop system has good reconfigurable performance.
