METHOD FOR COMPUTER-AIDED CLOSED-LOOP AND/OR OPEN-LOOP CONTROL OF A TECHNICAL SYSTEM

摘要

The invention relates to a method for computer-aided closed- and/or open-loop control of a technical system, wherein the technical system is described for a plurality of points in time by a state and an action carried out in said state. In the method, on the one hand, a first value of an output quantity is predicted on a data-based model from the state of the technical system at the current point in time. On the other, a second value of said output quantity is determined on the basis of an analytical model. In addition, the state of the technical system at the current point in time is assigned a confidence score which describes the confidence in the correctness of the prediction of the data-based model for the state of the technical system at the current point in time. Using the confidence score, a third value for the output quantity is determined which takes into account the first and second value as a function of the confidence score, the first value being more heavily taken into account the higher the confidence according to the confidence score. The technical system is closed- and/or open-loop controlled taking the third value into account. The method according to the invention is characterized in that, even for regions of the state space of the technical system in which the quality of the prediction of the data-based model is low because of a small set of training data, a suitable value for a corresponding output quantity of the technical system can nevertheless be derived taking an analytical model into account. The method according to the invention can be used for closed- or open-loop control of any technical systems such as e.g. turbines and, in particular, gas turbines.
