    • 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.
    • 本发明涉及一种用于技术系统的计算机辅助闭环和/或开环控制的方法,其中通过在所述状态下执行的状态和动作对多个时间点描述技术系统。 在该方法中,一方面,从当前时刻的技术系统的状态,在基于数据的模型上预测输出量的第一值。 另一方面,基于分析模型来确定所述输出量的第二值。 另外,在当前时间点的技术系统的状态被分配一个置信度分数,该置信度分数描述了当前时间点技术系统的状态对基于数据的模型的预测的正确性的置信度。 使用置信度分数,确定输出量的第三值,其考虑到作为置信度分数的函数的第一和第二值,根据置信度得分,第一个值被更多地考虑在更高的置信度上。 技术系统是封闭和/或开环控制的,考虑到第三个值。 根据本发明的方法的特征在于,即使对于技术系统的状态空间的区域,由于一组训练数据,基于数据的模型的预测的质量较低,所以适用于 可以考虑到分析模型,导出技术系统的相应输出量。 根据本发明的方法可以用于任何技术系统的闭环或开环控制,例如, 涡轮机,特别是燃气轮机。
