Method and Device for Determining a Parameter of a Model of a Technical Installation

摘要

Methods and devices for determining at least one parameter of a model of a technical installation are provided. In this case, the parameters are updated on the basis of measurements as a function of an observation matrix. The observation matrix is prescribed as a function of the model and being able, if appropriate, to depend on a time variable which can be measured.

1. A method for determining at least one parameter of a model of a technical installation, the method comprising:
initializing at least one parameter at a prescribed value; and repeatedly: determining an estimate of at least one physical quantity as a function of a previous value of the at least one parameter and of at least one part of an observation matrix; measuring the at least one physical quantity of the technical installation; determining an error value as a function of the estimate of the at least one physical quantity and of the measured value of the at least one physical quantity; and determining an updated value of the at least one parameter as a function of the preceding value of the at least one parameter, of the error value and at least of the part of the observation matrix, the observation matrix being an observation matrix prescribed as a function of the model.
