摘要
研究了一种横侧向控制律的设计方法;建立了无人机侧向运动小扰动方程,分析了某无人机的侧向零极点分布特点;分析了该无人机的稳定性、开环传递函数和操纵特性,通过分析比较该无人机在X轴转动惯量增大10倍前后的副翼和方向舵控制效率的变化,提出了利用方向舵控制滚转,副翼滚转增稳的控制方法,解决了由于该无人机X轴转动惯量小,副翼操纵效率高,易导致侧向控制发散的问题;仿真结果显示设计合理可行,可应用于同类无人机的控制律设计。
Researching a method of design of lateral control law.Analyzing the characteristics of UAV＇s lateral zero and pole distribution through establishing the lateralizing small perturbation equation of UAV.Through comparing and analyzing the variation of the aileron and rudder control efficiency before and after the UAV X axis of inertia increase 10 times changes,It is proposed that we can use the rudder to control roll,the aileron to increase stability of roll,through analyzing the UAV＇s stability,the open-loop transfer function and the handling characteristics.It can solve the problem that the high efficiency of aileron manipulation is easy to cause speread of lateral control because of small inertia of X axis.Simulation results show that design is rational and feasible,which can be applied in similar UAV flight control law design.
