Abstract: An anomaly detection module is configured to apply a plurality of machine learning models to received technical status data to detect one or more indicators of an abnormal technical status prevailing in the industrial process system. The plurality of machine learning models are trained on historic raw or pre-processed sensor data and the anomaly detection module configured to generate the anomaly alert based on the one or more indicators. The received technical status data is assigned to signal groups and the generated anomaly alert is a vector with each vector element representing a group anomaly indicator for the respective signal group. Each vector element is determined by applying a respective group specific machine learning model.

Abstract: A high-level motion controller provides a lower-level thrust allocation with generalized forces demanded on the ship for the current instant of time as well as a prediction of future generalized forces {{circumflex over (τ)}D}t=0T demanded over a predicted future time, and optionally one or more other reference predictions, such as a time-varying velocity and position of the ship {{circumflex over (η)}D, {circumflex over (ν)}D}t=0T. When predictions of the future desired forces and torque are made available to the lower-level thrust allocation, the lower-level thrust allocation will be aware of what is needed in the future and use the predictions to make efficient changes towards the desired future references, when it generates control signals to thrusters available in the thruster system to distribute the desired generalized forces into individual forces of the individual thrusters.

Abstract: A method and device for controlling a melting and refining process in an electric arc furnace for melting a metal, wherein the electric arc furnace includes molten and solid metal and a slag layer on the surface of the molten metal, wherein an electromagnetic stirrer is arranged for stirring the molten metal. The method includes calculating/determining masses of the molten and solid metal at a point of time, wherein the calculation is based on initial values of the molten and solid metal, an arc power supplied to the electric arc furnace, and temperatures of the molten and solid metal, determining a stirring power based on the calculated/determined masses, and supplying the determined stirring power to the electromagnetic stirrer.
