    Abstract :

    Liquid level control in tanks and between tanks are basic industrial problem. Often the tanks are so coupled in interacting and non-interacting way they exhibit non-linear behaviour. This paper deals with the level control of two tank system which are connected in interacting and non-interacting mode to control the level of system. In interacting mode the level of first tank will depend on the level of second tank while in case of non-interacting mode level of first tank is independent of level of second tank. Here comparative analysis of the transient response obtained by different controllers- Conventional controller PID, Feed forward-feedback controller, IMC (Internal Model Controller) and Fuzzy Logic Controller has been done using MATLAB simulation. It has been observed that IMC performs better than other controllers for both interacting and non-interacting mode.
