某型涡扇发动机分布式容错控制系统设计与试验验证
|
摘要
为了提高某型涡扇发动机控制系统的安全性和可靠性,提出1种分布式架构下的容错控制方案。基于模块级硬件冗余的思想,设计了包含7个智能节点的基于TTP/C(时间触发协议)总线的发动机分布式容错控制系统,可以实现核心控制节点的硬件备份。基于控制律重构的方法,采用模型参考变结构控制算法设计了容错控制器,可以根据系统故障情况将控制结构切换至无故障的控制回路中。搭建了涡扇发动机分布式容错控制系统硬件在环仿真试验环境,开展了容错控制系统的试验验证。结果表明:在核心控制节点故障时,容错控制系统可以在120 ms内快速启用热备份节点代替故障节点;在非核心控制节点故障时,容错控制系统可以在100 ms内完成控制回路的切换,并保证发动机各状态量不产生明显波动。
In order to improve the safety and reliability of a turbofan engine control system,a fault-tolerant control scheme based on distributed architecture was proposed. Based on the idea of module level hardware redundancy,an engine distributed fault-tolerant control system based on TTP/C(time trigger Protocol) bus was designed,which included seven intelligent nodes. The hardware backup of the core control node can be realized. A fault-tolerant controller was designed by using model reference variable structure control algorithm based on the reconstruction of control law. The control structure could be switched to a fault-free control loop according to the fault situation of the system. The hardware-in-loop simulation test environment of distributed fault-tolerant control system of turbofan engine was built,and the test verification of fault-tolerant control system was carried out. The results show that when the core control node fails,the fault-tolerant control system can quickly startover hot backup nodes to replace the fault nodes in 120 ms;In case of failure of non-core control node,the fault-tolerant control system can complete the switching of the control loop within 100 ms,and ensure that each state quantity of the engine does not generate obvious fluctuation.
