Study of PID and FLC based water level control using ultrasonic level detector

In the industrial sector there exist parameters like level, temperature, flow, vibration which needs precise control. Conventional control system adopts PID technique to control its parameter but cannot achieve desired accuracy because of several disadvantages. So to overcome these drawbacks, fuzzy logic control system is adopted which gives better performance. Therefore, an attempt has been made to study the comparison between conventional PID controller and Fuzzy logic controller using ultrasonic level sensor. In this paper, we have designed a real setup of microprocessor based PID controller as well as designed simulation system of PID and fuzzy logic controller for water level control by using Fuzzy Logic Toolbox and Simulink in MATLAB software.
