高超声速滑翔飞行器动态逆解耦跟踪控制方法研究

针对临近空间高超声速滑翔飞行器再入段俯仰偏航以及滚动三通道运动存在非线性耦合严重的情况,建立了高超声速滑翔飞行器的多变量强耦合非线性时变倾斜转弯控制模型,提出了一种将过载控制转化为所需迎角侧滑角及滚转角误差的三通道联合跟踪控制方法,根据高超声速滑翔飞行器制导回路快速性的动态性能要求,设计了一种基于非线性动态逆及状态反馈的解耦综合控制器,闭环仿真结果表明该方法能够实现三通道运动解耦控制和制导指令跟踪,满足系统动态性能的要求。

Research of Dynamic Inversion Decoupling Tracking Control Method for Hypersonic Sliding Vehicle

A multivariable and strong coupling nonlinear time-varying bank to turn control model was built for that there exists severe nonlinear coupling factors among the three channels including pitching, yawing and rolling respectively when the near space hypersonic sliding vehicle reentried. A tracking control method was presented based on that the overload command was transformed into the needed attack angle, sliding angle and rolling angle error command, combined with the requirement of the dynamic performance ...
