Abstract
This paper presents the design of PI controller using Decoupling and CRA technique for quadruple-tanks process. In case of, TITO interacting system such as quadruple-tanks process, the controller designs have been performed ambitiously because interferences between inputs and outputs. With the proposed method, The Decoupling controllers have been used for decreasing the cross coupling between inputs and outputs and transforming TITO plant transfer function into SISO form so that SISO controller for each SISO model can be designed easily and efficiently. Furthermore, Using CRA technique has made the output response achieve the required performance specification. Also, in non-minimum-phase, PI controller with inverted Decoupling can stabilize the system and minimize several undesirable influences from an interaction in TITO process. The results from control system design can be illustrated by the experiments. © 2011 ICROS.
