摘要：
In the semi physical simulation of aeroengine control systems，the reliability of surge sensor and instability detection system can be verified by simulating the high-frequency pulsating air pressure during com⁃ pressor stall，so as to avoid the high cost and high risk of forced surge test. Aiming at the coupling problem of pressure pulsation characteristics existing in the current pulsating pressure generator，a compressor stall pulsa⁃ tion pressure simulation method based on the characteristic decoupling control is proposed. Firstly，the overall de⁃ sign scheme of air pressure simulation system is put forward. Then，the comprehensive model of the air pressure simulation system is established，and the input and output characteristics of the system are analyzed by simula⁃ tion. On this basis，a combined control strategy of charging and discharging proportional valve and rotary valve is proposed. Finally，several groups of simulations and experiments are carried out aiming at the air pressure with different pulsation characteristics. The results show that the designed valve combination and characteristic decou⁃ pling control strategy realize the dynamic adjustment of pulsating air pressure in the range of pulsating frequency 0~200Hz，pulsating amplitude ratio 0~0.4 and reference pressure 800kPa，and can be used for the characteristic simulation of the stall pressure signal under various instability modes of the compressor. © 2023 Journal of Propulsion Technology.
