| 摘 要： | 基于动态逆和变结构控制理论设计了BTT无人机控制系统,首先应用时间尺度理论将控制系统分为快变量和慢变量两个子系统.在快变量子系统中以p,q,r]为子系统输出、以计算力矩l,m,n]为控制输入,再根据子系统输入解算出舵面偏转角,在控制律的设计中,应用动态逆理论进行输入输出线性化,再以计算力矩偏差为子系统摄动设计变结构控制律.在慢变量子系统中以α,β,μ]为子系统输出、以p,q,r]为控制输入,在控制律设计中,应用动态逆理论进行输入输出线性化,再以计算气动力偏差为子系统摄动设计变结构控制律.整个系统的设计中需要确定气动导数的上下界,控制律设计简单,易于工程实现.最后仿真分析得出,这种方法有较好的控制效果.

| Abstract: | A method of designing control system based on dynamic inversion(DI) and variable structure control(VSC) applied to Bank-To-Turn(BTT) Unmanned Aerial Vehicle(UAV) is proposed.Firstly,the control system is divided into two subsystems based on timescale techniques.In the fast-variable subsystem,are considered to be outputs,calculated aerodynamic moments are considered to be inputs,then the actuator surfaces are calculated,in the design of control law,the subsystem is linearized based on dynamic inversion,then ... |
