takes place outside the lqg controller component 30 for the parameterization of the lqg controller 30 a time constant t 100 which describes the superheater dynamic behavior at full load is needed a change in the steam temperature u03b8 nk at the superheater entry affects the live steam temperature u03b8 d in such a way as described by a delay through three pt 1 elements each having a time constant t 100 a time constant t mess which describes the behavior of the live steam temperature measurement is also needed the behavior of the controller is parameterized by means of the two setting values r and r k which describe the sensitivity of the state controller and of the kalman filter fig3 shows a model of the superheater section in the superheater 6 comprising three pt 1 elements 34 in the following a pt 1 element 34 is understood to be a linear transmission element which has a first order time delay the three pt 1 elements 34 represent the transmission behavior of a delay from the specific enthalpy h nk at the entry to the superheater 6 that is following the cooler 12 to the specific enthalpy h d of the live steam 10 in this context it is enthalpies rather than temperatures that are used for calculation since the assumption of linear behavior is then justified the quotient of t 100 and the load signal la serves as the time constant t u00fch for the pt 1 elements 34 wherein the load dependent dynamic behavior of the superheater.
