摘　　要：通过对植保无人机飞行过程气流场进行分析,建立了植保无人机飞行过程姿态动力学模型,利用非线性模型对其飞行姿态进行预测,并设计了飞行系统控制器,对飞行过程中的气流进行动态感知,及时进行飞行姿态的调整。仿真分析结果表明,基于气流特征建立的植保机飞行控制系统能够有效提高植保机在飞行过程中的姿态控制稳定性,可为相关设计提供参考。Based on the analysis of the air flow field in the flight process of the plant protection UAV,this paper establishes the attitude dynamic model of the flight process of the plant protection UAV,uses the nonlinear model to predict its flight attitude,and establishes the flight system controller to sense the air flow in the flight process and adjust the flight attitude in time.The simulation results show that the flight control system based on the air flow characteristics can effectively improve the attitude control stability of the plant protection aircraft in flight,which can provide a reference for the relevant design.
