This paper describes the controller design of non linear system.The Non linear system taken up for the study is the Interacting Conical Tank Systems.In this paper, design of controllers based on Skogestad tuning is determined.For each stable operating region, a first order process model is identified using Process reaction curve method.The control is done and the responses for different operating regions are taken.Simulation is made by the MATLAB software.
