摘　　要：针对高空模拟试车台进气系统负温试验过程中的温度压力耦合难题,利用耦合参与矩阵与线性变参数模型的方法,对系统的耦合特性进行了定量分析与总结。首先,通过耦合参与矩阵对系统线性化后的单个平衡点进行耦合特性分析,并通过仿真对比系统阶跃响应以验证方法的有效性。其次,在此基础上,利用线性变参数方法对负温试验任务下的耦合特性进行仿真、分析和总结系统的耦合特性,为后续基于耦合分析的控制设计奠定了工程理论基础。Aiming at the temperature-pressure interaction analysis of altitude ground test facility(AGTF)in the negative temperature simulation,the interaction characteristics of the system with the participation matrix(PM)and linear variable parameter(LPV)model were analysed and summarized.First,PM was adopted to analyze the interaction characteristics of the equilibrium point of AGTF,and the results were verified by comparing the system step response.On this basis,the LPV was used to analyze the interaction characteristics under continuous simulation,laying the engineering theoretical foundation for the controller design based on coupling analysis.
