Abstract

STUDY OF APPLICATION OF FUZZY-PID DRUM LEVEL CONTROL FOR BOILER

Dr. C. Nagarajan, P. Johnlouis*, N. Balasubramaniyan and M. Hari

ABSTRACT

Boiler unit plays essential role in power plant and controlling the boiler drum level is one of the important operations. Nowadays, conventional Proportional plus Derivative plus Integral (P+I+D) control is being used for this purpose. These conventional controllers in power plants are not very stable when there are fluctuations. To overcome this and to get better solution intelligent controller (fuzzy logic) is used to tune the conventional PID controller automatically in online process through LabVIEW platform. In addition, Conventional PID and Hybrid Fuzzy-PID controllers are compared. Hybrid Fuzzy-PID controller result proves that, it offer better performance (in terms of settling time, rising time, steady state error) than conventional PID controller in boiler drum level control.
