Abstract (en)
[origin: WO2013072464A2] The invention relates to a method for controlling a temperature (ϑD) of steam (8) for a steam power plant (2). A state regulator (30) controls the temperature (ϑD) of the steam (8) at an outlet of a superheater (6) using a feedback of multiple medium states of the steam (8) in the superheater. The aim of the invention is to achieve a stable and precise control of the steam temperature. This is achieved in that the state regulator (30) is a linear regulator, the feedback matrix of which is ascertained such that the regulator has the control quality of a linear-quadratic regulator.
