A compression algorithm based on wavelet networks for historical data of process control system is developed. The method＇s implementation and computing steps are described in detail. The simulation results show that the features of algorithm are fast parameter approximation rate and high compression ratio when the method is applied to the compression decompression process of pressure signals from a paper mill. It is feasible to apply wavelet networks for signal processing of process control system.
