Recent advancements in process industries have enabled the development of combination of interacting and non-interacting of process tank level control system. An experimental setup of three tank level process in interacting and non- interacting mode was studied, to obtain the process models. Different control schemes such as Internal model controller (IMC), IMC-PID and Proportional –Integral and Derivative (PID) were implemented. The goal of the model-based controller is to compensate for shifts in the process and maintain the liquid level on target. The performance of different control schemes were investigated through computer simulation.
