ABSTRACT

This study adopts the centrifugal compressor system which produces the nitric acid equipment in China Petrochemical Development Corporation’s Plant. The system is non-linear and its manufacturing process is changeable, which the traditional PID (Proportional-Integral-Differential) control method is difficult to apply. This study is intended to apply the artificial neural network method to test and forecast the compressor performance. By means of collecting the PLC (Programmable Logic Controller) on-line data, the proposed method is applied to simulate the control system. According to the result of this study, the proposed method can reach the high accuracy, and make concrete contributions in promoting the safety of the centrifugal compressor system.
