Temperature and Water Level Control in Boiler by using Fuzzy Logic Controller

C. DINAKARAN

Abstract


Boiler is the main component in generating steam in Thermal & Nuclear power generation units and its control is very important. Water level control is more important such as boilers in Thermal & Nuclear power plants. This work proposed a simple fuzzy logic based water level controller. The fuzzy logic controller uses the MAMDANI type Fuzzy Inference System. The fuzzy controller has two inputs, feed backs from temperature sensors and water level sensor is given to the fuzzy controller and the controlled output is generated for output valve position. The fuzzy controller is implemented in MATLAB and then simulated in SIMULINK to test the behavior of the system when the two input changes. The response of the fuzzy controller is then compared with a conventional PID controller. In control systems there are a number of generic systems and methods which are encountered in all areas of industry and technology. The results are shown sequentially and the effectiveness of the controller is illustrated.
