摘　　要：为更好地发挥微波着陆大范围着陆制导的优势,设计了一种新型的微波着陆横向轨迹自动生成控制律,可根据飞机初始位置和姿态生成一条进近轨迹并控制飞机沿此轨迹对准跑道中心线;提出了单圆、S型和直接指数进近3种进近模态,并分别对3种模态设计了控制律。仿真结果表明,所设计的控制律能够指引飞机在不同初始条件下对准跑道。In order to wake full use of the advantages of microwave landing system （MLS） on wide-range landing guidance, an MLS lateral auto-landing control law with automatic path definition was designed, which could generate an approaching trajectory according to the aircraft＇s initial position and attitude and control the aircraft towards the nmway centerline. Three approaching modes were proposed： single circular, S shape and direct centerline approaching. The control laws for the three approaching modes were designed. Simulation shows that the control laws can guide the aircraft towards the centerline of runway under different initial conditions.
