Method and device for creating a model of a technical system from measurements

摘要

The invention relates to a method for creating a model of a technical system as a function of measured sensor data of the technical system, comprising the following steps: initializing a symbolic regression problem. A list of mathematical functions is established, comprising at least one linear and / or non-linear functions and / or at least one-dimensional parameterizable characteristic curve. The at least one-dimensional characteristic is implemented by a smoothed grid regression (SGR) model. Solving the symbolic regression problem using a genetic algorithm.
