PARAMETER CONTROLLING OF BOILER IN POWER PLANTS USING FUZZY LOGIC CONTROLLER

Santanu Das, Sridhar Raja

Abstract: Boilers are used industrially both for electric power generation and for supplying process stream in thermal power plants and its control is very important in many field applications. In some situation conventional PID control technique is being used for control purpose. These conventional controllers are not well suitable for some unusual conditions like load disturbances. Fuzzy logic control technique is being used to overcome these problems. A closed loop control system incorporating fuzzy logic has been developed for a class of industrial control systems. A unique fuzzy logic controller (FLC) structured with an efficient realization and a small rule base that can be easily implemented in existing industrial controllers. Fuzzy logic control system is much closer to human thinking and natural language than traditional control systems. This paper describes a fuzzy control technique and its implementation in boiler controls. Here a PIC microcontroller is being used where fuzzy control algorithm is implemented.
