Abstract

In this paper, the development of a water bath temperature system to control the liquid´s temperature in the water bath will be presented. In order to develop the water bath temperature control system, MATLAB fuzzy logic toolbox will be utilized. The Fuzzy Logic Controller (FLC) is designed to control water temperature based on the input acquired from the thermal transducer sensor. The inference engines that are used are; Max-min (Mamdani) method and centre of gravity technique for defuzzification. The 4 × 4 matrix rules for the controller will be used in this project. In addition, the USB NI-DAQ card will be used as xPC target to link the MATLAB software and real time application. The real time output temperature is validated based on the simulation´s temperature which is initially set by user. It can be concluded the performance of real time study is in par with the simulation result.
