Decoupler and PID controller design of TITO systems

Nordfeldt, Pontus LU and Hägglund, Tore LU (2006) In Journal of Process Control 16(9). p.923-936
Abstract
This paper treats controller design and tuning for systems with two input signals and two output signals in the process industry. Two design methods that can be combined to form a core in an algorithm for automatic design and tuning for the considered systems are presented. The proposed controller consists of a decoupler and a diagonal PID controller. The decoupler has the property that as little dynamics as possible is introduced in the decoupler. The PID design method is based on exhaustive search. The methods are combined and tested in an industrial environment in a paper mill. (C) 2006 Elsevier Ltd. All rights reserved.
