Abstract:

In view of the situation that the grid-connection of air supply compressor units of the Altitude Test Facility (ATF) in China mainly adopts manual operation, an expert system based on manual operation experience was proposed, and the grid-connection simulation and related experiments were conducted. We developed dynamic simulation models for the compressor, ducting, heat exchanger and butterfly valves of different diameters, a dynamic simulation model of the butterfly valve actuator based on the continuous action position signal of the butterfly valve, as well as a rule-based expert system based on a historical operating dataset. The dynamic simulation model of the air supply compressor unit of the ATF was built with the MATLAB/Simulink platform, and a grid-connection control simulation was carried out. Experimental results indicate that the average relative errors of the compressor inlet pressure, compressor outlet pressure, and the pressure ratio were 3.12%, 0.44%, and 3.23%, respectively. In the process of grid-connection, the maximum and minimum pressure ratios in the experiment were 3.69 and 2.27, respectively, satisfying the safety requirements of the unit and proving the reliability of the control strategy.
