摘要: 针对某推力矢量姿态控制（TVC）飞行器，在助推段需要连续绕弹体纵轴滚动（自旋）飞行的新问题，在研究其非线性飞行动力学建模和动力学特性的基础上，通过分析研究和数值仿真，找出了影响俯仰偏航飞行稳定和姿态控制精度的主要交叉耦合因素．重点突出曾被忽视的因自旋滚动引起底层伺服系统之间的惯性延迟耦合，提出了工程可实现的解耦控制方案和算法．可为进一步研究该类复杂飞行器的飞行控制提供模型和方法上的理论指导和参考．

Abstract: A new kind of problem for TVC vehicle spinning in the boost stage is researched. On the basis of research of the non-linear flying dynamics modeling and dynamic properties of TVC vehicle, the dominant coupled factors which affected the attitude stability and attitude precision of pitch channel and yaw channel were found. The inertial delay coupled effects between pitch servo system and yaw servo system were emphasized, which were ever neglected, and the uncoupled plan and control algorithm were put forward from the point of engineering realization. It is to provide the theoretical guidance and reference for the furthermore research of this complicated flying control.
