随着民用飞机自动驾驶功能的完善,仪表着陆系统渐渐进入人们视野中。自动飞行航向道模式是飞机仪表着陆系统中重要的模式之一,其代替飞行员对飞机水平姿态位置进行控制。介绍了飞机自动飞行控制系统航向道(LOC)进近模式控制律设计。当飞机截获LOC波束信号后,该控制律能够导引飞机自动跟踪LOC波束中心线进近。以某型飞机为控制对象,进行了控制律设计和数字仿真,仿真结果表明该控制律具有可行性,具有良好的应用前景。
With the improvement of the automatic piloting function of civil aircraft, the landing system of the instrument gradually enters the people’s field of vision. The automatic flight course mode is one of the most important modes in the aircraft’s instrument landing system, which replaces the pilot’s control of the aircraft’s horizontal attitude. This paper introduces the control law design of the approach approach mode of the aircraft’s automatic flight control system. When the aircraft intercepts the LOC beam signal, the control law can guide the aircraft to automatically track the approach of the LOC beam centerline. The control law design and digital simulation are carried out on a certain type of aircraft. The simulation results show that the control law is feasible and has good application prospects.
