A commonly occurring control problem in the chemical process industries is the control of fluid levels in storage tanks, chemical blending and reaction vessels. In this paper we are addressing model identification of simple coupled two tanks, which are coupled by a valve. We have found practically the model by using MATLAB environment, which gives results almost identical to ideal model of plant. Quantitative Feedback Theory (QFT) is a frequency domain design method applied to design a robust controller for this system. We have practically tested this controller with adding disturbances and set point changes in the process. Designed robust QFT controller gives best results inspite of plant uncertainty and disturbances. Keywords—Hybrid Coupled Two tanks, Model, Quantitative Feedback Theory (QFT), Robust Control.
