摘要
针对大气层外质量矩控制自旋拦截器的特点,建立了具有一个可任意活动质量块的拦截器六自由度动力学数学模型;并基于带有一个沿径向运动质量块的姿态动力学模型,分析了姿态控制机理及结构参数对姿态控制效果的影响,通过仿真验证了分析的有效性,为拦截器姿态控制系统的设计奠定了基础。
According to the character of extra-atmospheric mass moment control spinning interceptor, a sixdegree freedom dynamic mathematical model of the interceptor is established in this paper, which possesses a random moving mass. At the same time, based on attitude dynamic mathematical model with a radial moving mass, the principal of attitude control and the control effect which is caused by the structure parameter are also analyzed, in addition the analysis is validated by simulations, so a basic design of interceptor attitude control system is established.
