摘　　要：针对采用扰流片控制的旋转稳定弹道修正弹,为寻求合理、高效的控制方案设计,必须尽可能准确地获取扰流片气动参数,故有必要开展该类修正弹的扰流片气动参数辨识研究.在设计及扰流片附加力和力矩的飞行动力学模型基础上,利用最小二乘准则建立目标函数,以扰流片的轴向力系数、法向力系数、静力矩系数为待辨识参数,以带自适应变异算子的差分进化算法为全局优化工具,构建了扰流片参数辨识的总体方案及流程.仿真结果表明:所构建辨识方案可有效辨识扰流片的气动参数;测量数据噪声对参数辨识精度有一定的影响.For a spin-stabilized trajectory correction projectile controlled by a micro-spoiler,in order to find a reasonable and efficient control scheme design,the aerodynamic parameters of the micro-spoiler must be obtained as accurately as possible,so it is necessary to carry out a micro-spoiler aerodynamic parameter identification research for trajectory correction projectiles.The overall scheme and flow of micro-spoiler parameter identification are constructed on the basis of the flight dynamics model considering the additional force and moment of the micro-spoiler,the objective function is established by using the least square criterion,with the axial force coefficient,normal force coefficient and static moment coefficient as the parameters to be identified,and with the differential evolution algorithm containing adaptive mutation operators as the global optimization tool.The simulation results show that the proposed scheme can effectively identify the aerodynamic parameters of the micro-spoiler,and the measurement data noise has a certain influence on the parameter identification accuracy.
