| 摘 要： | 针对大型空间飞行器的大角度姿态控制问题,考虑航天器惯量矩阵中的不确定性和外部扰动力矩,应用高阶滑模控制方法设计了姿态跟踪控制律.采用的二阶滑模控制方法改善了系统针对不确定性及外部扰动的鲁棒性,并减弱了振颤现象.针对所设计的控制器进行了仿真验证,并与一阶滑模控制进行了对比,仿真结果表明了所提出方法的有效性.

| Abstract: | For the large angle attitude control of large-scale spacecraft with uncertainties in the inertial matrices of spacecraft and the external disturbance torques, attitude tracking control laws are designed based on higher-order sliding mode control technique. With the second-order sliding mode control used in the design, the robustness of the system with respect to uncertainties and external disturbances is improved, and the chattering phenomena are attenuated. For the designed controllers, numerical simulations are carried out, and compared with first-order sliding mode controllers. The simulation results show the effectiveness of the proposed method. |
