针对变体飞行器在大包线内变形飞行的姿态镇定问题,提出了一种基于双信号切换的鲁棒变增益切换控制方法。在分析飞行器跨包线区域变形飞行特性的基础上,基于多胞权值速率有界约束给出了时变参数多胞系统稳定的充分条件,进一步研究了飞行器具有包线和构型双信号切换多胞系统的特征,分析了跨包线区域变形飞行的稳定性;设计了鲁棒变增益切换控制器,从而保证系统在包线内的稳定性及鲁棒H_∞性能。
Aiming at the problem of attitude stabilization of variant aircraft in deformed maneuvering in large package line, a robust variable gain switching control method based on double signal switching is proposed. Based on the analysis of the deformation flight characteristics of the aircraft across the covered area, the sufficient conditions for the stability of the time-varying parameter multicellular system are given based on the bounded constraints of the rate of the multiple cells. Further studies on the two-signal switching of the aircraft with envelope and configuration The characteristics of the multi-cell system are analyzed. The stability of the transformable flight over the covered area is analyzed. The robust variable gain switching controller is designed to ensure the system stability and robust H_∞ performance in the covered area.
