摘　　要：为实现某型无人机定速飞行功能以提升用户操控体验,通过分析无人机实际飞行观测数据,采用系统仿真拟合反向参数辨识方法获取发动机模型参数,构建无人机飞行速度-发动机转速的闭环PI控制策略并选定合适的控制参数。经仿真测试和实际飞行验证,该方法得到的发动机模型参数可用于无人机飞行速度-发动机转速的闭环控制设计,能够满足无人机定速飞行实际使用要求。In order to realize the constant speed flight function of a UAV and to improve the user’s control experience,the engine model parameters are obtained by analyzing the actual flight recorded data of UAV and utilizing fitting inverse parameter identification method of system simulation,and the closed-loop PI control strategy of UAV flight speed and engine rotation speed is constructed,and the appropriate control parameters are selected. Through the simulation test and actual flight verification,the engine model parameters obtained by this method can be used in the design of the closed-loop control of UAV flight speed and engine rotation speed,and they can meet the actual operation requirements of constant speed flight of UAV.
