航空发动机容错控制系统设计

航空发动机是一个结构复杂、非线性强的多变量控制对象.控制系统的高可靠性是最重要的技术指标之一.而容错控制为提高系统的可靠性、可维护性和有效性开辟了一条新途径.文中介绍了基于航空发动机容错控制的基本原理和方法,研究了控制系统在反馈信号故障情况下的容错控制问题,该系统可以对失效的检测数据做出实时估计并反馈信号,从而达到对故障容错的目的.

The fault tolerant control system of aero-engine

Aeroengines are complicated,non- linear and multi- variable control systems. In the condition of feedback sensor failure, the fault tolerant control is also deeply researched in this paper. When feedback sensor is in failure, the system could do the real- time estimation through the detected data of the fault sensors and feedback the signals, thus fault tolerance is achieved.
