基于分块反步设计的飞行器姿态稳定鲁棒控制

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。

Robust Attitude Control of Aircraft Based on Partitioned Backstepping

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.
