In order to improve the control precision of plating bath temperature, an intelligent temperature control system for plating bath based on computer was designed. A fuzzy PID temperature controller was designed to adjust the parameters of PID controller in real time. The dynamic matrix was used to calculate the past and present time deviations and predict the future deviations, thus obtain the best input. Finally, an experimental study was carried out. The results showed that the intelligent temperature control system for plating bath has some advantages of fast convergence rate, high precision and good stability, which can meet the demands of electroplating industry and has a broad application prospect.
