Design and Simulation of Aero Control Law with Balanced-Autopilot

摘要:

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。

Abstract:

The aero proportional control law of the automatic pilot would bring control stability error under interference moment or ramp signal, airplane then can't make airplane accurate fly along scheduled flight path. Firstly, basic work principle 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.
