      针对高超声速飞行器模型具有高度非线性和易变的动态特性, 应用保护映射理论提出了一种高超声速飞 行器大包线控制律设计方法. 首先, 结合间隙度量理论建立高超声速飞行器线性变参数(linear parameter-varying, LPV) 模型, 然后设计控制器结构并计算初始点的控制器参数, 并根据保护映射理论分析初始控制器使闭环系统稳 定的参数区间, 通过迭代运算自适应地获得满足性能要求的控制器参数集合. 仿真结果表明, 建立的LPV模型具有 良好的精确度; 所设计的大包线控制律能够满足高超声速飞行器的性能要求, 并且保证系统在飞行域内全局稳定.
英文摘要
      To deal with the high nonlinearity and variable dynamic properties existing in the hypersonic vehicle model, we apply the guardian maps to propose a method for designing the control law for the wide flight envelope of hypersonic vehicles. Firstly, we use the gap-metric principle to build a linear parameter-varying (LPV) model for the hypersonic vehicle. Then, we select the structure for the controller and calculate the controller parameters for the initial point. Furthermore, according to the guardian maps, we analyze the interval of the parameter at the initial point for the close-loop system to be stable, and find out a set of allowable control parameter values by adaptively using iterative operations, such that the performance requirements are satisfied in the expected flight process. Simulation results show that the established LPV model maintains a good accuracy, and the control law ensures the global stability throughout the wide flight envelope for the hypersonic vehicle, making the system fulfilling the prospective performance demands.
