An electrochemical reactor and its temperature control system suitable for molten salt electrochemical tantalum anodizing process are designed, and the application of fuzzy parameter self-tuning PID controller in the electrochemical reactor temperature control system is studied. The conventional PID controller and the fuzzy parameter self-tuning PID controller are simulated and compared. The results show that the overshoot of the PID controller system based on fuzzy parameter online self-tuning is significantly reduced, and the dynamic and static performance of the control system are improved. The field experimental results also prove that the design scheme is reasonable and effective. Keywords molten salt electrochemical reactor; temperature control; parameter self-tuning; fuzzy PID controllerAbstract The design of an electrochemistry furnace for melting-salt electrochemistry tantalum anodic oxidation process and its temperature control system is introduced in this paper. The application of the parameter self-tuning fuzzy proportional-integral-derivative (PID) controller in this temperature control system is studied. In comparison with the conventional PID temperature control system, the simulation results indicate that the electrochemistry furnace with the parameter self-tuning PID controller has high control precision, good dynamic and static performances. The spot experiment result shows that the design has good practicability and validity.Key words melting-salt electrochemistry furnace; temperature control; parameter self-tuning; fuzzy PID controller
