| 摘 要： | 利用经典控制理论中的根轨迹法对某固定翼无人机纵向控制律进行分析设计。首先通过在定常直线无侧滑模态下对无人机数学模型进行配平线性化,将飞机运动分解为纵向运动和横侧向运动;再利用俯仰角速率和俯仰角双回路反馈实现俯仰角控制回路;之后通过分析系统附加开环零点对系统稳定性和动态性能的影响确定高度积分增益实现高度控制回路,利用Matlab进行了仿真,给出了仿真结果。仿真结果表明控制参数设计合理,根轨迹法是设计飞行控制律有效而成熟的方法。

| Abstract: | The method of using the root locus of the classical control theory to analyze and design a fixed-wing UAV's portrait control law is introduced. First,the aircraft motion is decomposed into longitudinal motion and lateral motion according to the plane's little perturbation linearization equations. Second,the pitching holding is realized by using angle rate and angle for double loop feedback control. Then the altitude holding is designed through the analysis of system additional zeros on system stability and ... |
