This paper introduces the basic composition and working principle of the constant temperature and constant pressure air supply control system for turbocharger test bench. The AMESim simulation model of the constant pressure air supply control system is established using PCD pneumatic element library, and the model parameters are set. The dynamic characteristics of the outlet pressure are simulated and analyzed to ensure that the control system meet the requirements of the outlet absolute pressure and accuracy of 49 010 kPa. On this basis, the PID controller is used for correction and optimization analysis. Simulation results show that the control system can meet the requirement of constant outlet pressure.
