This work studiesthe design and simulation of a water level and temperature controller using Proportional Integral Derivative (PID) Controller and Fuzzy logic (FL) Controller. The simulation of the design system was achieved by utilizing MATLAB and Simulink. The experiment displayed some challenges of methods, non-linear PID Controller and fuzzy logic (FL) in the system designed. PID controllers were implemented separately to control the water level and temperature with deferent parameters. howeves the (FL) process was implemented to control both, water level and temperature. The challenges with this method lead in the tuning and selection of the fuzzy sets. The experiment showed that both control systems are important in their own right. The two controllers used to combine the system in order to improve the accuracy and precision of the result. Results demonstrated that more accurate response was obtained using a PID system, which did not show any study state error, whereas Fuzzy Logic Controller is relatively easy as compared to the Proportional Integral Derivative Controller with the despite of complex mathematical modeling.
