摘要： The invention relates to a method and to a corresponding device for determining at least one model parameter of a control engineering model of a steam generator, wherein a control engineering model structure having the at least one characteristic model parameter is predetermined for the steam generator. Measurement signals of the steam generation process are recorded online. According to the invention, the at least one model parameter is estimated online. For this purpose the same input signal is applied to both the real process and the model of the steam generator. Next, an estimability analysis is carried out, wherein at least one output signal of the respective process and/or model, or at least one input signal, are processed by a comparative evaluation on the basis of a gradient analysis. Estimation ranges within which a valid parameter estimation is possible are defined in a further step on the basis of the gradient analysis. If the estimability is positively assessed, the current estimated value of the at least one model parameter is improved and furthermore the model is adapted by means of the estimated values in an iterative process. The invention further relates to a control unit for a steam generator and to a computer program product.
