Most of the industrial systems exhibit non-linear nature. Conventional controllers are not able to provide good and accurate results; so fuzzy logic control can be used to obtain better response. A model for simulation is designed and all the assumptions are made before the development of the model. An attempt has been made to analyze the efficiency of a Type1 and Type-2 fuzzy controller over conventional proportional integral derivative controller for a multi tank interacting water level control system and their responses are compared. Analysis is done through computer simulation using Matlab/Simulink toolbox. This paper shows the application of Type-1 and Type-2 Fuzzy Logic Controller which gives the better response.
