Constant Potential Algorithm for Cathodic Protection based on Fuzzy Control

In order to improve the control effect of potentiostat in cathodic protection project, a logic algorithm was designed based on fuzzy control theory, and an accurate two-dimensional fuzzy query table was put forward. It is proved that the effect is better than PID algorithm by using Matlab to simulate. The stability of potentiostat was improved, the steady-state errors were reduced, and the overshooting was inhibited. The prototype used in a water filtration system of a nuclear power plant runs well and exhibits good prospects.
