| 摘 要： | 建立了有纵向单滑块的变质心再入飞行器系统控制模型。对该有输入非线性的快时变多体系统,考虑系统存在参数不确定等因素的影响并将完整的活动质量体动力学环节置入姿态控制,基于滑模控制理论设计了俯仰姿态跟踪鲁棒控制系统。在参数不确定性条件下对飞行控制系统进行了仿真。结果表明：设计的控制律可实现对指令角度和指令位置有效、快速、稳定...

| Abstract: | The control model of the reentry vehicle with a moving point mass was established in this paper.While the parameter uncertainties and other factors of the system were taken into account and the dynamic of the whole moving point mass was put into the attitude control for this fast time varying multi-body system with nonlinear input,the robust adaptive control system of the pitch attitude tracking was designed based on sliding mode control theory.The simulation results of the flight control system under param... |
