Abstract
A method for controlling a temperature of steam for a steam power plant is provided. A state regulator controls the temperature of the steam at an outlet of a superheater using a feedback of multiple medium states of the steam in the superheater. An aim herein is to achieve a stable and precise control of the steam temperature. This is achieved in that the state regulator is a linear regulator, the feedback matrix of which is ascertained such that the regulator has the control quality of a linear-quadratic regulator.
