摘　　要：单通道鸭舵控制是弹药智能化的一种重要控制方式。分析了新增鸭舵对弹体产生的力和力矩,建立了基于一对鸭舵控制的有控外弹道模型,推导了鸭舵控制力矩对弹体攻角的控制方程,研究了两种常用的舵机控制波形对弹体攻角的影响。经仿真对比表明,采用两状态控制波形和三状态的控制波形对弹体的周期平均效果相似,但两状态控制较三状态控制引起的弹丸攻角的摆动幅度更大,震荡过渡时间更长。此结论对于有控弹药控制方案设计提供一定参考。Canard control is a main way to projectile control in single channel mode. The force and moment from canard was analyzed, the control projectile ballistics model based on canard was established, control equation with canard was educed, and three state rudder and two state rudder influence on angle of attack was researched. The simulation results show that the period-average-force of the two rudders are similar, but the three state rudder will lead to more wiggle on projectile and longer interim, which can reference for project.
