摘　　要：从降低制导武器成本和体积的角度出发,在GPS接收机和x轴陀螺仪等少量信息的基础上,根据双旋弹的抛物线飞行特性,提出一种基于调整固定翼鸭舵控制力矢量方向进行弹道修正的制导算法。此种制导方式并不需要精确的弹体姿态信息,通过GPS接收机数据估算弹体的当前姿态,并通过弹体的静稳定裕度保证飞行稳定性,实现落点偏差的有效修正。最后在分析姿态信息采集算法的误差范围的基础上,对制导控制算法的适用性进行了分析与验证。According to the parabolic flight characteristics of the dual-spin projectile, a guidance algorithm was proposed for the purpose of reducing the cost and volume of guided weapon from the perspective of controlling the direction of the control force vector of the fixed canards based on GPS receiver and x axis gyroscope. With no need for precise attitude information, the current attitude information in the proposed guidance method was computed by GPS receiver with flight stability realized by the static stability of the body,resulting in a correction of point difference. Finally,the applicability of the guidance control algorithm was analyzed and verified through an analysis of the error range of the attitude acquisition algorithm.
