十字型鸭翼子弹药控制系统研究

为解决子弹药的杀伤效能低的问题，提出了一种十字型鸭式子弹药并对其进行控制系统的分析与设计.针对子弹药不断旋转摆动的问题，分析了子弹药控制力的产生原理，提出一种周期平均控制力的方法，建立了旋转摆动子弹药数学模型.为验证子弹药的飞行稳定性，应用Matlab软件进行了无控飞行轨迹仿真，得出子弹药水平位移为450 m，攻角变化在0.4°以内，满足稳定性要求.由于子弹药控制通道间具有较强耦合作用，设计了一种特殊的前馈补偿法来对子弹药进行解耦，设计了PID控制器对子弹药控制效果进行了仿真，结果表明解耦后控制通道间的耦合效果基本消失. 

Research on the Control System of Cross Typecanards Ammunition

To solve the problem of low killing efficiency of submunition,a kind of cross-shapedcanard bullets and its control system were proposed,analyzed and designed.For the problem of rotating submunition,the generation principle of the control force of submunition charge was analyzed,and the method of cycle average control force was put forward.To verify the flight stability of submunition,the Matlab software was used to do a simulation of the flight path without control.The horizontal displacement of submunition was 450 m,and the angle of attack was within 0.4°.Due to the strong coupling effect of submunition control channel,a pre-feedback compensation method was designed to decouple su bmunition and a PID controller was designed to simulate the control effect.Research results show that the coupling effect almost disappeares after decoupling.
