Abstract

In this paper, a class of MIMO systems is shown, for which the linearizing feedback can be evaluated without prior solving partial equations. Every nonlinear component in the system of this class is separated from respective control signal by one equation. It is always possible to linearize two equations by every control. However, in this case, the remaining equations will be also linearized. This class of systems is relatively narrow, but it is often seen in thermal plants. The control of fluid flow usually incorporates a nonlinearity of product or square root type. These cases were studied by Bourles et al. (1997) and Bolek et al. (2000). In this paper, a model of a fossil-fuelled power plant is shown as an example
