Abstract—The air separation plays an extremely important role in the development of metallurgical industry. And the air compressor which provides not only the required pressure air for the cooling equipment and refrigeration plant but also the raw material required for the separation plant is a key device in the air separation plant. Utilization of the air compressor is extremely extensive in many significant departments such as the metallurgy, oil and chemical industry. The air compressor system is a timevarying, delay and nonlinear complex system. Defects in the traditional control method and controller lead to the pressure instability of the compressed air outputted from the air compressor in volatile gas-consumption situations, sometimes a wide range of fluctuation arising, for gas consumption in the industrial field is irregular. Therefore, the working state of the air compressor becomes unstable. In general, electric energy consumption of the air compressor system working in the stable state counts up to about twenty percentages of the total energy consumption in the enterprise. Moreover, energy consumption in the unstable state is more. It results in both a waste of resources and greater energy consumption. Therefore, guaranteeing the output pressure of the air compressor system steady is extraordinarily significant for improving efficiency and saving energy for the overall air separation system. The turbine compressor system was taken as the research object to analyze its characteristics and control requirements. DCS control technology applied to the system, the ECS-700 system of SUPCON was utilized into configuring the air compressor system and monitoring real-time values of important parameters in the various components. According to the working characteristics of the air compressor system, the fuzzy control theory, as one of the modern control theories, was applied to the constant pressure control system to design a fuzzy pressure controller. The simulation results showed that the controller not only was more convenient and effective but also provided a certain directive significance and reference for control of other parameters of the air compressor system.
