Method and Device for Measuring a Technical System on a Test Bench

Abstract

A method that is at least partially computer-implemented is disclosed, for preconditioning a technical system on a test bench for presetting a system state to a desired value of at least one state variable. The method includes (i) specifying a measurement trajectory or validation trajectory for measuring the technical system, wherein the measurement trajectory or validation trajectory specifies a desired start value or start value range of at least one specified state variable, (ii) providing a data-based surrogate model that is trained to describe the behavior of the technical system and assign measurement points of a trajectory to a respective system state, (iii) performing an optimization method based on a target function defined as a function of the desired start value or the desired start value range of the at least one predetermined state variable and an estimated end value of the at least one predetermined state variable of a conditioning trajectory, in order to determine the conditioning trajectory such that the estimated end value of the at least one predetermined state variable corresponds as closely as possible to the desired start value of the at least one predetermined state variable or lies within the desired start value range, wherein the estimated end value of the at least one predetermined state variable results from applying the surrogate model to the conditioning trajectory, and (iv) operating the technical system using the conditioning trajectory to set the system state to the desired value.
