I-P controller design for quadruple-tank system

Abstract

A control system design with Coefficient Diagram Method (CDM) is proven that effective for SISO control design. But the control system design for MIMO via CDM is not concrete procedure. In this paper presents the control system design method for quadruple-tank process via CDM. By using the decentralized method for both non-minimum phase and minimum phase are made. The results from Integral-Proportional (I-P) controller's design via CDM and standard Proportional-Integral (PI) controls are also shown to compare the merits of the proposed controllers. © 2004IEEE.
