过载/迎角边界保护是电传飞机一项最重要的飞行包线保护功能。针对某型飞机,在典型控制增稳结构的基础上,引入积分控制结合比较大小转换逻辑的控制律实现对过载/迎角的精确控制,同时对控制参数的分析、确定方法进行了详细分析研究。仿真结果表明,积分控制与比较大小的控制逻辑结构完全满足过载/迎角边界保护的功能要求。
Overload / AOA boundary protection is one of the most important flight envelope protection features for Telex aircraft. For a certain type of aircraft, the control law of integral control combined with the size-conversion logic is introduced to realize the precise control of overload / angle-of-attack based on the typical control of stabilizing structure. At the same time, the analysis and determination of control parameters are analyzed in detail . The simulation results show that the integral control and the comparatively small control logic structure fully meet the functional requirements of overload / AOA boundary protection.
