摘　　要：针对制导迫击炮弹的固定翼鸭舵导航初始化,设计了基于GPS信息的衰减记忆法扩展卡尔曼滤波算法,用于实时求解固定翼鸭舵的气动力合成矢量,然后结合固定翼鸭舵的气动数学模型,设计了固定翼鸭舵的导航初始化算法。并在直流电子负载系统的基础上设计了鸭舵的旋转控制算法,通过仿真试验验证了依靠GPS提供的位置速度信息和鸭舵滚转角速度信息可以快速实现固定翼鸭舵的导航初始化,为旋转控制固定翼鸭舵的工程应用,提供了理论参考。When roll control guided munitions are launched, the roll angle of canards may not be initialized under high impact. Therefore the navigation initialization of roll control .fixed canards must be .finished when the munitions are stable in flight. The attenuation memory-extended Kalman.filter algorithm based on GPS information is designed to solve the real-time aerodynamic vector of fixed canards, and then the aerodynamic mathematical model of fixed canards is combined to design real-time estimation algorithm for canards roll angular. In the simulation experiment, the DC electronic load system is used to control canards rotation. The experimental results show that the navigation initialization of fixed canards can be .finished only by GPS information and canard roll rate, and the initialization algorithm is suitable for engineering application.
