Abstract: An exemplary method for controlling an electrical converter includes receiving an actual electrical quantity relating to the electrical converter and a reference quantity; determining a future state of the electrical converter by minimizing an objective function based on the actual electrical quantity and the reference quantity as initial optimization variables; and determining the next switching state for the electrical converter from the future state of the electrical converter. The objective function is iteratively optimized by: calculating optimized unconstrained optimization variables based on computing a gradient of the objective function with respect to optimization variables; and calculating optimization variables for a next iteration step by projecting the unconstrained optimization variables on constraints. The computation of the gradient and/or the projection is performed in parallel in more than one computing unit.

Abstract: An exemplary system includes a first electric motor and a second electric motor, which are coupled mechanically to one another via a common string of the system. The string has a torsional natural oscillation at a natural frequency. A first oscillating torque acts on the string by the first electric motor and a second oscillating torque acts on the string by the second electric motor. The second electric motor is arranged with respect to the first electric motor such that the effect of the second oscillating torque on the string results in damping of the excitation of the natural oscillation owing to the first oscillating torque.

Abstract: A device for installing a modular crawler into an air gap of rotating electrical machinery and removing the crawler from the air gap has a reconfigurable handle attached to a curved head made from metallic material. The crawler is magnetically attached to the curved head when it is desired to insert the crawler into the air gap or remove the crawler from the air gap. The head can be rolled in the field into the curvature needed to match the stator's inner surface so that the installation device can easily be inserted in the air gap. The handle has several joints that can be adjusted in the field as needed for the best reachability. A camera is mounted on the curved head so that an operator can see the interface region between the curved head, crawler and air gap.
