模型预测控制算法在飞翼无人机中的应用研究

摘要

For a small tailless flying-wing UAV, the CFD method is used to investigate the aerodynamic charac teristics of the UAV and calculate the aerodynamic derivatives and controlling derivatives. A simulation model of model predictive control is established. Utilizing dynamic matrix control algorithm, the autonomous flight con trol system is designed and analyzed. Simulation and flight test results show that under the constraint conditions with input and output, the dynamic matrix control algorithm has obvious advantages and certain application val ue for engineering.%针对某小型无尾飞翼布局无人机,运用CFD方法分析了该无人机的气动特性,计算了气动导数及操纵导数,建立了模型预测控制算法的仿真模型,并运用动态矩阵控制算法设计了飞行控制系统.仿真分析与试飞结果表明,在具有输入输出等约束条件下动态矩阵算法优势明显,具有一定的工程应用价值.
