Abstract
A method for controlling the temperatures of steam for a steam power plant is provided. A state controller, in order to output a desired steam temperature as a controlled variable, feeds back several steam states in a superheater for superheating steam using a monitor, which calculates the steam states, and the desired steam temperature is forwarded to a further controller for controlling the temperature. In order to achieve a stable and accurate control of the steam temperature, it is proposed that the state controller be a linear quadratic controller.
