To configure the control agent (POL), pre-given training data is read in, specifying the state dataset (S), action dataset (A), and the obtained performance values ​​(R) of the technical system (TS). Based on this training data, a data-driven dynamic model (NN) is trained to reproduce the obtained performance values ​​(R) based on the state dataset (S) and action dataset (A). Furthermore, a action evaluation process (VAE) is trained to reproduce the action dataset (A) based on the state dataset (S) and action dataset (A) after information reduction, where reproduction errors (DR, D0, D1) are determined. To train the control agent (POL), training data is fed to the trained dynamic model (NN), the trained action evaluation process (VAE), and the control agent (POL). Here, the performance values ​​(R1, R2) output by the trained dynamic model (NN) are fed into a pre-given performance function (P). Additionally, the reproduction errors (D0, D1) output by the trained action evaluation process (VAE) are fed into the performance function (P) as parameters affecting performance reduction. In this way, the control agent (POL) is trained to output an action dataset (A) that optimizes the performance function (P) based on the state dataset (S).

This invention discloses a method and system for designing robust operating conditions for industrial production processes. Considering various uncertainties in industrial production, and addressing scenarios where process mechanism models are unknown or simulation costs are high, this method utilizes only the input and output data of the production process. By constructing a robust Bayesian optimization model, it can determine nominal operating condition setpoints with strong disturbance resistance for the production process. The implementation process is as follows: sampling and testing within the operable range of the operational variables to obtain process output data; defining constraints, constructing the robust operating condition design problem as an optimization proposition that minimizes the maximum constraint value; establishing a Gaussian process regression surrogate model based on the sampled data, and constructing a sampling function that integrates the predicted mean, uncertainty, and constraint satisfaction probability; employing a two-stage Bayesian optimization framework, iteratively sampling and updating the model until convergence is achieved to obtain the robust operating condition setpoints.
