飞行模拟器自动着陆系统的建模与仿真

Modeling and Simulation of Flight Simulator Automatic Landing System

对飞行模拟器自动着陆系统进行了研究。现有的研究多集中在进近阶段,而对接地、拉平以及复飞阶段的研究不够,或并没有统一在相同的控制结构中,使得自动着陆系统的功能和性能无法满足高等级飞行模拟器的指标要求。为了完善自动着陆控制过程,提出了一个完整的自动着陆系统控制律算法,基于典型飞行控制系统体系结构,分别建立了制导回路和姿态回路的控制模型,并进行仿真。算法结果能够满足自动着陆过程中所有飞行阶段对控制算法的功能要求和性能要求,仿真结果表明了控制算法的有效性。

Automatic landing system of the flight simulator has been studied.Existing studies focus on the approach phase,while the study on the ground leveled and the missed approach phase is not enough,or is not uniform in the same control structure.Therefore,automatic landing system function and performance can not meet the requirements of identified high-grade flight simulators.A complete algorithm for automatic landing system control law is propose,based on a typical flight control system architecture.The models of guidance loop and attitude control loop are established respectively.The algorithm can satisfy all the functional requirements and performance requirements of automatic landing phases of flight control algorithms,Simulation results show the effectiveness of the control algorithm.
