An Application of the Virtual Reference Feedback Tuning Method for Multivariable Process Control

Abstract

This paper describes an application of the virtual reference feedback tuning (VRFT) method for multivariable process control. The VRFT method is a direct method which determines parameters of a feedback controller using a set of input and output data of a plant. Originally, the VRFT method is presented for a design of a single-input single-output control system. In this paper, the VRFT method is applied for a design of a multi-input multi-output system. Experimental test is carried out and test results show availability of the VRFT method.
