基于分块反步设计的飞行器姿态稳定鲁棒控制

Robust Attitude Control of Aircraft Based on Partitioned Backstepping

采用分块反步设计思想,结合输入状态稳定性理论,获得了一种具有鲁棒性能的飞行器姿态稳定控制方案。该方案可自然地处理姿态耦合问题,实现半全局姿态稳定控制,并对外部扰动具有鲁棒性,可直接应用在燃气动力的情况。对某空间飞行器的姿态控制系统进行了数值仿真,仿真结果验证了该方法的有效性。

This paper proposes a robust nonlinear attitude control method for aircraft based on partitioned backstepping method and input-to-state stability theory, With this strategy the coupling of the model attitude can be dealt naturally, A stable attitude control is realized semi-globally and the scheme has a good robust property subjected to external disturbances. The control design can be applied directly to an aircraft with thrust arising from gas fuel. A numerical simulation of an attitude control system is performed and the simulation results show that the control method designed in this paper is effective.
