Method and Device for Determining Control Parameters for Controlling a Technical System

Abstract

A computer-implemented method for determining parameter values of parameters of an optimized parameter set for operating a particular technical system is disclosed. The behavior of the parameterized technical system can be simulated by way of operational variable profiles indicating time profiles of at least one input variable, at least one output variable and at least one status variable. The method includes the steps of providing a data-based representation model trained to associate operational variable time profiles of one or more technical systems with a latent representation vector in each case that characterizes the behavior of the technical system, and providing a data-based distribution model trained to associate latent representation vectors resulting from simulated operational variable profiles of the particular technical system with a probability distribution of parameter values of the parameters of the parameter sets. And the following steps are carried out iteratively (i) providing parameter values of an initial parameter set or selecting parameter values of a parameter set from a probability distribution of parameters by way of random selection, (ii) simulating or measuring the technical system parameterized with the parameter values of the parameter set in order to obtain operational variable time profiles, (iii) analyzing the obtained operational variable profile with the data-based representation model to obtain a latent representation vector, and (iv) further developing or retraining the data-based distribution model with a training data set from the obtained latent representation vector and the parameter set so that an updated probability distribution of parameters results from the data-based distribution model.
