Research on fuzzy PID-based variable frequency control technology of electroplating power supply

To improve the intelligent level of electroplating power supply control system and meet the demand of electroplating products of various kinds, this paper designs a fuzzy PID algorithm-based electroplating power control system. The system, with fuzzy PID algorithm and variable frequency speed control technology as its core, applies fuzzy algorithm to adjust PID parameters in real time to control the inverter output frequency with a purpose to change the power supply of the motor speed, to improve the quality of current modulation, and to adapt to different plating load. The test proves that the transformed power supply control system can ensure its rapidity and accuracy of current regulation under different loads, and has strong ability to restrain disturbance. In addition, the power control can be carried out both in the field and on remote clients and therefore increases its flexibility.
