Non-linear process control is a difficult problems in process industries. Conical tank level control is one among them. Real processes often exhibits nonlinear behavior, time variance and delays between inputs and outputs. Conical tanks are widely used in many industries due to its shape which provides easy discharge of water when compared to other tanks.. Moreover, liquid level control of a conical tank is still challenging for typical process control because of its nonlinearities by a reason of constantly changing cross section area. In this paper the mathematical modeling of three tank conical interacting and non-interacting system is designed by Wiener model PI controller(WMPI) where the tuning rules based on Chidambaram method and the performance criteria are related with Internal mode controller(IMC). Also in this paper we analyze dynamic behavior among interacting and non-interacting system.
