某型飞机纵向运动 MATLAB 建模及仿真研究

摘要

In order to design a type of aircraft flight control system , it establishes the nonlinear mathematical model for aircraft longitudinal motion , takes the small perturbation method to model linearization , obtains the lin-earization mathematical model based on S function of MATLAB .At last, it realizes the simulation and analysis for the aircraft longitudinal motion control system design .%为设计和研究某型飞机飞行控制系统，首先确定了该飞机纵向运动的非线性数学模型，然后基于小扰动法将该非线性模型线性化，再基于MATLAB S函数实现线性化后的数学模型，最后基于PID控制方法对飞机纵向运动设计控制器并进行仿真分析。
