摘要
研究非线性离心力对刚_柔耦合系统的大范围姿态运动的影响· 首先从离心力势场的概念出发,推导了刚_柔耦合系统的非线性模型;然后通过近似计算分析了非线性离心力对系统姿态运动的动态效应;最后,在只有系统姿态与姿态速率测量值的条件下,基于能量范数选择Liapunov函数。
The influences of nonlinear centrifugal force to large overall attitude motion of coupled rigid_flexible system was investigated. First the nonlinear model of the coupled rigid_flexible system was deduced from the idea of 'centrifugal potential field', and then the dynamic effects of the nonlinear centrifugal force to system attitude motion were analyzed by approximate calculation; At last, the Liapunov function based on energy norm was selected, in the condition that only the measured values of attitude and attitude speed are available, and it is proved that the PD feedback control law can ensure the attitude stability during large angle maneuver.
