Temperature-pressure interaction analysis of altitude ground test facility's air intake system in negative temperature simulation
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.
