模型参考自适应电传飞行控制系统纵向控制律设计

摘要

针对电传飞行控制系统中被控对象模型参数时变的特点,应用模型参考自适应控制方法设计纵向控制律.论述飞机纵向运动的动力学模型和参考模型的建立,以及基于此参考模型用超稳定性理论设计自适应控制律的方法,并且通过仿真试验进行控制性能验证.仿真结果表明,所设计的控制律可以根据飞行状态的不同自适应的调节控制律,控制性能指标满足飞行品质规范要求,设计方法可行.%In order to deal with time variability of the fly-by-wire (FBW) flight control system, longitudinal movement control law was designed based on the theory of model reference adaptive control. How to establish a longitudinal movement model and a reference model and how to design adaptive control law with hyperstability theory were illustrated. Simulation was done to validate the performance of control law. Simulation results show that the designed control law can adaptively be regulated on different flight conditions,the control performance can satisfy flight quality criterion and this method is availability.
