研究了高超声速飞行器的动态解耦问题。首先利用张量-积（TP）模型变换方法，得到了HFV的线性变参（LPV）模型，并将其平滑地转化为多边形形式。然后，通过最小化由被控系统和无耦合参考模型组成的虚拟系统的H∞范数，推导出一种动态解耦控制方法。基于线性矩阵不等式，给出了控制器存在的充分必要条件。其次，设计了HFV多面体LPV模型的解耦控制器。仿真结果表明，该方法具有较好的动态解耦性能。
The dynamic decoupling problem of the hypersonic flight vehicle (HFV) is considered in this paper. The Linear Parameter-Varying (LPV) model of the HFV is firstly obtained and smoothly transformed into a polytopic form by the Tensor-Product (TP) model transformation method. After that, a dynamic decoupling control method is derived by minimizing the H∞ norm of a virtual system, which is composed by the controlled system and the no coupling reference model. The necessary and sufficient condition for the existence of the controller is derived based on Linear Matrix Inequalities (LMIs). Next, the decoupling controller for the polytopic LPV model of HFV is designed. And the simulation results show that the proposed method has perfect performance in terms of dynamic decoupling.
