Novel high-power copper electrolytic rectifier based on auto-disturbance rejection controller

Aiming at the nonlinear characteristics of copper electrolytic system, this paper designs high-power thyristor electrolytic power supply current control system based on auto-disturbance rejection controller, the internal disturbance and external disturbance of system can be observed, and use them to offset the system using auto disturbance rejection controller. It improves the stability of the electrolytic rectifier system and control precision. The engineering practice shows that the rectification systems improve the quality of copper electrolysis well and reduce the energy consumption of the whole system.
