摘要
针对质量弹簧系统，提出一种基于状态监测和故障诊断（ＣＭＦＤ）的可重构和容错控制设计方法。重构和容错策略是根据ＣＭＦＤ和重构逻辑来切换预先设计的４ 个控制器。仿真表明，该控制方法能有效地保证速度和位移的跟踪性能以及系统的稳定性。
A novel fault tolerant-reconfigurable control(FTRC) methodology is presented based on condition monitoring and fault diagnosis (CMFD) for the inherent dynamic changes and the anticipated faults of a mass-spring system.The strategy of the FTRC is that the four pre-designed controllers are switched according to the results of CMFD and switching logic. Simulations show that the proposed control scheme can insure the controlled system to be stable and have a good tracking performance of position and speed.
