舰载飞机纵向着舰自抗扰导引系统设计

为使舰载飞机沿着理想的下滑轨迹安全着舰,自动着舰系统必须具备跟踪甲板运动和抑制气流扰动的性能。因此,采用自抗扰控制器(ADRC)设计了纵向着舰导引系统。仿真结果表明,自抗扰导引系统不但对典型输入的跟踪性能令人满意,而且抑制突风扰动的能力较强;和PID导引律相比,系统响应的品质有较大的改善。

Design of Airplane Longitudinal Carrier Landing Active-Disturbance-Rejection Guidance System

In order to make carrier-based airplane land on a carrier safely along an ideal flight path,the automatic carrier landing system(ACLS) must have the ability to trace the deck motion and restrain air turbulence.So active disturbance rejection controller(ADRC) was used to design the longitudinal carrier landing guidance system.According to the simulation results,the guidance system's performance of tracing the typical input is satisfactory,and its ability of restraining the gust is strong.Compared with the PID guidance law,the response characteristics have been improved greatly.
