摘要: 针对高超声速飞行器的不确定性问题,提出了基于线性-非线性切换自抗扰控制的方向舵高精度调节策略.首先,推导出面向姿态控制的攻角系统模型;其次,利用连续光滑函数bas(·)代替自抗扰控制中分段连续函数fal(·),并分析增益特性;最后,基于函数bas(·)设计线性-非线性切换扩张状态观测器,提出了线性-非线性控制律的平滑切换规则.此外,对控制参数进行实时估计从而提供更准确的干扰观测和补偿精度.结果表明,相比单一的线性或非线性自抗扰控制,该调节策略抗干扰能力更强,实现了方向舵高精度调节的目标.

Abstract: A high precision rudder adjustment strategy based on linear-nonlinear switching active disturbance rejection control is proposed for hypersonic vehicles with strong uncertainty. Firstly, the angle of attack system model for attitude control is derived. Secondly, the piecewise continuous function in active disturbance rejection control is replaced by a continuous smooth function , and the associated gain characteristics are analyzed. Finally, a linear-nonlinear switching extended state observer is designed based on the function , and a smooth switching rule of linear and nonlinear control law is proposed. In addition, control parameters are estimated in real time to provide better accuracy of disturbance observation and compensation. The results show that the proposed adjustment strategy has stronger anti-disturbance ability than single linear and nonlinear active disturbance rejection control, and achieves the goal of high precision rudder adjustment.

Key words: hypersonic vehicles, uncertainty, linear-nonlinear switching active disturbance rejection control, ruder adjustment
