Process identification of Multi-Input Multi-Output process ranks as one of the important tasks in PI controller design. The closed loop behaviour of MIMO process decisively depends upon the identified process model. Nevertheless, the process identification of MIMO process is a demanding task, since there exists interaction, nonlinearities and process noise. However the controller design is given significance rather than obtaining a mathematical model of the process. In this paper, an attempt has been made to design a controller not based on process model, but simply from three areas of the process open loop step response. The proposed tuning method stands out to be pretty simple, with the simulation results depicting comparable or even better closed loop responses than the simple and comprehensive BLT (Biggest Log modulus Tuning) method.
