航空发动机双余度控制规律设计方法

Method of dual-redundant control law design for aero-engine

提出了航空发动机双余度控制规律设计概念和一种利用双余度控制规律作为控制传感器信号故障处理策略的方法;建立了备份控制规律设计方法和设计原则,应用于某高性能涡扇发动机双余度控制规律设计研究之中.研究结果表明:双余度控制规律可以实现无扰动转换,重构控制回路,提高发动机的任务可靠性.该方法可以应用于配装数字式电子控制系统的各类发动机.

A concept of dual-redundant control law design for aero-engine was proposed and a method of utilizing dual-redundant control law for the control sensors signal fault processing policy was derived in the paper.The technique and principles of the backup control law design were built and applied to the dual-redundant control law design and research of one high performance turbofan engine.The study result indicates that the dual-redundant control law can be made undisturbed conversion and control loop reconfiguration,so that mission reliability of engine is improved.The means may have application in all kinds of engine which is equipped with digital electronic control system.
