航天器相对姿态跟踪的非线性前馈控制
Nonlinear Feedforward Control for Spacecraft Relative Attitude Tracking
摘要
Abstract
The spacecraft relative attitude kinematics and dynamics based on modified rodrigues parameters(MRP) were proposed in the presence of serious nonlinear and controller design complexity during spacecraft relative attitude tracking control. A nonlinear feedforward controller was designed using Lyapunov method. The control law can not only ensure global asymptotic steady of close-loop system, but also make relative attitude tracking errors converge to zero field speedily. By using Matlab/Simulink programming, the modeling and simulation of spacecraft relative attitude tracking were discussed. Numerical simulations are exploited to verify the effectiveness of the model and control law.关键词
