Abstract


In this study, output voltage of automatic transformer-rectifier (TR) unit of impressed current cathodic protection has been controlled by using fuzzy logic controller. To prevent corrosion, voltage between the protection metal and the auxiliary anode has to be controlled on a desired level. Because soil resistance in the environment changes with humidity and soil characteristics, TRs must control the output voltage between protection metal and auxiliary anode automatically. In this study, a fuzzy logic controller has been developed for tuning output voltage of TR units. PIC16F877 has been used to control the output voltage of the TR unit. The output voltage has not overshot and oscillated.
