Feedback linearization of multi-input thermal plants

Abstract

In this paper a multi-input nonlinear plant is considered. A new linearization technique is examined that transform the nonlinear system into an equivalent linear system. In this method one of control signals is made as a linear combination of states. The linearization technique based on feedback is applied for such systems. It is shown, that there are systems, which are only linearizable when using approach presented in this paper.This class of systems is relatively narrow, but is often seen in thermal plants. An example of heat exchanger was examined in order to illustrate developed procedure.

A New Feedback Linearization Method for Mimo Plants

“…In paper (Bolek and Sasiadek 2001) a certain structure (3) of a plant was found, where such attitude is suitable.…”

“…In paper (Bolek and Sasiadek 2001) a similar problem was examined. But the class of linearizable systems was restricted to two input systems.…”
