Design of water level controller using fuzzy logic system

Singh , Harshdeep (2013) Design of water level controller using fuzzy logic system. BTech thesis.



Water level control is highly important in industrial applications such as boilers in nuclear power plants. In this work a simple water level indicator and a water level controller based on fuzzy logic is proposed. The fabricated electronic level indicator defines 2 levels minimum and maximum through LEDs. The fuzzy logic controller is based on Mamdani type Fuzzy Inference System. The fuzzy controller has two inputs, error in level and rate of change of error and one output, valve position. The fuzzy controller is implemented in MATLAB and then simulated in Simulink to test the behavior of the system when inputs change. The response of the fuzzy controller is then compared with a conventional PID controller. The results are shown sequentially and the effectiveness of the controller is illustrated.
