Design and Simulation for Vertical Guidance Law Design of Flight Guidance System

摘要:

为了提高机动性能, 现代飞机的设计开始向放宽静不稳定乃至静不稳定的方向发展, 因此飞行控制律的设计尤为重要;以大型民用客机的开发设计为应用背景,根据飞行仿真的需要,采用非线性动态逆的方法建立了飞机的线性模型,并结合PID控制对飞机的垂直引导方面的控制系统进行分析和设计研究,最后配合Matlab/Simulink 数值仿真方法和Stateflow工具对所设计的控制律进行PID 调参仿真;仿真结果表明:所设计的控制律可以达到所要求的控制精度,具有良好的动态品质。

Abstract:

In order to improve the motor performance,the control law design is particularly important in modern airplane design because it is developed into static instability for higher mobility. This paper is based on the flight simulation needs, using nonlinear dynamic inversion method to bulid the linear model of the aircraft, and then using the PID control theory to analyze and design system of the plane for the horizontal guidance with the large civil aircraft design as the application background. Using Matlab/Simulink numerical simulation method and the Stateflow tool for PID adjusting parameters and simulating. The analysis shows that the controller can achieve the required control accuracy well and has the good dynamic quality.
