Research On Automatic Control System Of Electroplating Production Based On PLC

Electroplating Technology is electroplating surface engineering content of the most important one,is made in industrial chain indispensable a link.As a result of electroplating layer with functionality,and anti-corrosion decorative role,in all of the industry is widely used.In China with science and technology and made a surprise fly into the fierce advanced manufacturing rapid development,companies in order to improve their market competition,need to improve product quality at the same time as cut costs,improve production efficiency.In this paper,the technology and control requirements of the electroplating line are analyzed in detail in view of the low automation level and backward production equipment of the industrial electroplating line control system.,design a set of appropriate industrial electroplating production line automatic control system,the system uses PLC as the controller,through the control system hardware selection optimization,and according to the process and control requirements for system optimization,fundamentally solves the electroplating production line running instability and low efficiency.This paper,by using fuzzy control does not need accurate mathematical model and the principle of combining the classical PID closed-loop control and loop instead of the original open-loop control,with fuzzy control algorithm to build a “speed of fuzzy PID controller”.To influence the speed control of electroplating production for this paper,the proposed method is verified by MATLAB simulation and the feasibility and the superiority of inaccuracy,solved the traffic running vehicle running error is big,fixed a problem with long time driving speed,so as to improve the efficiency and effectiveness of electroplating production.Finally discussed the factors influencing the stability of the system to another,namely the precise control of the bath temperature,based on the research of the galvanizing production line temperature control system,analysis of the temperature characteristic of alkaline zinc plating,expert PID control is put forward to replace the original single closed-loop control method,using PID module of PLC internal adjustment,has realized the accurate control constant temperature bath temperature,and through the MATLAB software simulation verify the reliability and advantage of expert PID.
