带有非线性内模补偿的挠性航天器姿态控制
Attitude control for flexible spacecraft with nonlinear internal model compensation
摘要
Abstract
A novel robust attitude controller with nonlinear internal model compensation is proposed for the disturbance rejection and vibration suppression problems of flexible spacecraft attitude control. A novel nonlinear dynamic disturbance compensator is designed via internal model principle aiming at achieving asymptotic rejection to the time-varying disturbances generated by a nonlinear exosystem. A robust attitude controller is proposed to stabilize flexible modes based on angular velocity feedback control by analyzing the characteristic of the interconnected structure of rigid-flex system and using Lyapunov technique,and the convergence of the system state variables including flexible modal variables is guaranteed. The proposed controller is easy to be implemented because <br> only the attitude angle and angular velocity other than modal variables are applied. The effectiveness and robustness of the controller are demonstrated by numerical simulation for flexible spacecraft attitude control.关键词
