1. A method for operating a technical apparatus having an electronic converter that is controlled by at least one control signal, the method comprising:
providing a control signal profile of the at least one control signal to a control signal model block and a prediction block, the control signal profile suitable to operate a converter component of the electronic converter when the control signal profile is provided directly to the converter component;
predicting a predicted control signal profile based on the provided control signal profile using the prediction block, the predicted control signal profile being a predicted future profile of the at least one control signal;
providing the predicted control signal profile to the control signal model block;
obtaining a modified control signal profile of the at least one control signal by modifying the provided control signal profile using a trainable, data-based control signal model of the control signal model block, the trainable, data-based control signal model being trained to determine the modified control signal profile based on the provided control signal profile and the predicted control signal profile; and
providing the modified control signal profile of the at least one control signal directly to the converter component of the electronic converter in order to operate the electronic converter using the modified control signal profile.
