质量矩拦截弹通过驱动变质心执行机构改变导弹质心,进而改变其姿态角,从而实现对拦截弹的机动控制。文中从质量矩拦截弹的动力学问题入手,建立了非线性动力学模型,并对变质心执行机构运动情况进行了理论分析及仿真研究,分析研究了引入变质心执行机构对拦截弹带来的转动惯量、力矩和状态耦合的影响情况,对影响拦截弹快速响应以及耦合特性的主要因素进行了分析,并进行仿真验证,为研究质量矩拦截弹的控制律和实际应用打下基础。

The's mass-center changes with mass motion, and then the attitude angles change, thereby; the missile could be controlled to attack target. A coupled nonlinear system equations proposed based on the characteristics of the dynamics, with the analysis of the mass servo system, inertia moment and the coupling of the states researched. A series of simulation aboutmissile attitude performed so as to lay a foundation developing the control mechanism and application of the missiles.
