飞机均衡式自动驾驶仪控制规律设计及仿真

飞机在干扰力矩或斜坡信号作用下，其比例式自动驾驶仪控制规律会产生控制静差，难以控制飞机按预定航迹准确飞行。为解决该问题，首先，简要分析均衡式自动驾驶仪基本工作原理；然后，建立了均衡式自动驾驶仪结构图，对其控制规律进行设计；最后，进行了大量仿真研究。仿真结果显示，所设计均衡式自动驾驶仪控制规律是良好的和有效的，与比例式自动驾驶仪控制规律相比，其控制系统的稳态性能得到有效改进。

Design and Simulation of Aero Control Law with Balanced-Autopilot

The aero proportional control law of the automatic pilot would bring control stability error under interference mo-ment or ramp signal, airplane then can＆#39;t make airplane accurate fly along scheduled flight path. Firstly, basic work princi-ple foundation of the balanced-automatic pilot was briefly analyzed. Secondly, structure diagram of balanced-automatic automatic pilot was established, and it’s control law was designed. Finally, a great deal of simulation research was done. Simulation results manifested that the designed balanced-automatic pilot control law was good and valid, with comparison proportional control law of automatic pilot, and the steady state capabilities of the control system with balanced-automatic pilot were gotten valid improvement.
