研究了双微机型调速器电液控制系统的容错控制技术，分析了硬件重组、控制律重构和信号重构3种容错方法，理论分析和试验结果表明；容错控制可以进一步提高系统的可靠性。
The fault tolerant control technology of electro-hydraulic control system of dual-microprocessor-based governor was studied. Three kinds of fault tolerant methods including hardware reconfiguration, control law reconstruction and signal reconstruction were analyzed. Theoretical analysis and experimental results show that fault-tolerant control can further improve the system’s reliability.
