Abstract : This study develops a modified Linear Matrix In-equality with a PI controller to manage the multivariable process and maintain the effective liquid level system. The proposed method is designed by converting the PI into state feedback, and then the problem is determined using the convex optimization problem. The controller synthesis is reduced to an equivalent static output feedback control problem. Further, access to model the auto-tuned PI controller to control a class of multivariable systems using ideal decoupler and linear matrix inequality. The proposed control technique is validated on the quadruple tank system containing flow ratios operating the structure in minimum and non-minimum phase systems.
