质量矩再入飞行器的参数优化和性能分析

 为满足模型的有效性和可操作性，提出了以个体为对象的质量矩再入飞行器（MMV）动力学分析方法，即依靠内力和过载等物理量定性分析并设计主要参数后，再写出姿态、滑块完整动力学方程。该方程在保证MMV机动性不变的前提下，降低了系统耦合性；以驱动滑块运动的内力为控制量的简化方程是仿射型非线性方程，与精确方程的状态响应相比迎角偏差在0.01°以内，因此该方法降低了自动驾驶仪的设计难度。

Parameter Optimization and Performance Analysis of Moving Mass Actuated Reentry Vehicle

To ensure the validity and maneuverability of the model,the dynamic analysis approach of moving mass reentry vehicle (MMV) is proposed based on the single-body. This approach designs attitude dynamics parameters relying on qualitative analysis,by using overload and internal forces,and then writes attitude and moving mass kinetics complete equations. These equations can guarantee the MMV mobility,and reduce coupling of the system. The simplified equations are affine nonlinear equations. Compared with the att...
