Abstract: In the developed process industries, currently numerous demanding control issues are present because of rapid dynamic changes in process parameters. These changes might be occur since the process characteristics are connected with linear behavior, limitation of process variable and manipulated variable values during operation. Liquid level control in tanks and between the tanks are elementary industrial difficulty and also most essential needs. In many cases, the tanks are connected in parallel and series manner and reveal non-linear distinctiveness. This paper deals with the level control of two tank system which is connected in interacting and non- interacting mode. This paper demonstrates the optimized performance of Internal Model Control (IMC) and modified Internal Model Control (MIMC) for the system connected in interacting and non-interacting tanks in terms of transient response characteristics.
