摘要
针对先进气动布局飞行器飞行包线大、非线性不确定性强、耦合严重等问题给飞行控制带来的挑战,提出了一种基于扩张状态观测器(ESO)的轨迹线性化控制方法,给出了控制器的结构和设计方法,并应用于飞行控制律的设计。仿真结果表明,该方法实现了非线性不确定系统的解耦控制,对系统不确定性和外部干扰具有较强的鲁棒性。
The complex nonlinear, uncertain and coupled aerodynamic characteristics, which challenge the flight control system design for the advanced configuration aircraft with large flight envelope. A trajectory linearization control method based on expanded state observer （ESO） is presented. The framework and design scheme of the controller are described and are applied to design a flight control law. The simulation re- sults demonstrate that the controller can achieve the decouple control for nonlinear uncertain system and is robust to uncertainty and disturbance.
