摘要:

针对现代高速飞行器长细比愈发增大导致弹性振动频率低、振动方程系数大,气动伺服弹性日益突出的问题,提出一种基于改进扩张状态观测器(extended state observer, ESO)的弹性振动主动控制方法。通过构建基于ESO的弹性状态观测器,实现弹性状态在线估计,并在控制方程中引入补偿控制,实现对弹性振动的快速有效抑制。通过六自由度仿真验证了该方法的有效性和正确性,仿真结果表明,所提方法能够有效地对弹性振动进行主动抑制,提高了飞行控制系统对弹性振动的鲁棒性。

Abstract:

To address the increasingly prominent issue of elastic vibration in modern hypersonic vehicle—characterized by low elastic vibration frequencies, large vibration equation coefficients, and heightened aerodynamic servo elasticity due to ever-increasing aspect ratios, an active control method for elastic vibration based on an improved extended state observer (ESO) is proposed. Elastic state observer based on improved ESO is designed, which can online estimate the elastic state. Then Introduce compensation control into the cootrol equation to achieve rapid and effective suppressior of elastic vibration. The correctness and validity of the proposed method are shown via the six-degree-of-freedom of the hypersonic vehicle. Experimental results indicate that, the proposed method can actively suppress the bending vibration effectively and quickly, and the robustness of the flight control system to the elastic vibration can also be improved.

Key words: hypersonic vehicle, elastic vibration, extended state observer (ESO), active elastic control
