An apparatus, method and computer program for controlling propulsion of marine vessel. The propulsion is implemented by a foil wheel propulsion system. The method includes: receiving a wheel operation status from a wheel drive; receiving a plurality of foil operation statuses from a plurality of foil drives; receiving a command from a vessel control system; generating wheel control data for the wheel drive to control a foil pitch function of the foil wheel propulsion system based on the command in view of the wheel operation status; and generating foil control data for the plurality of the foil drives to further control the foil pitch function of the foil wheel propulsion system based on the command in view of the wheel operation status and the plurality of foil operation statuses, wherein a reference torque of the foil control data for each foil drive is generated using a foil feedforward model.

A drive arrangement for a cycloidal marine propulsion unit including at least two electrical blade motors each associated to a respective blade for pivoting thereof, each blade motor being operationally coupled to a respective blade drive for actuating the corresponding blade motor. The at least two blade drives each include a respective blade drive power converter operationally coupled to a first common intermediate DC-link, wherein the at least two blade drives being configured to feed power from the first common intermediate DC-link to their respective blade motors, and to feed regenerative power from their respective blade motors to the first common intermediate DC-link. The disclosure also concerns a marine propulsion unit having such a drive arrangement, and a method of operating such a drive arrangement.

An electromagnetic bearing arrangement for a rotating equipment includes an electromagnet; an amplifier arrangement based on IGBT (Insulated-Gate Bipolar Transistor) switches; a power supply; a controller; and a position sensor. The controller includes a position control module and a direct force control module, the position sensor is operatively connected to the control module to calculate a force reference (F) based on the measured position of the rotating equipment. The electromagnetic bearing arrangement includes a sensor for measuring at least one parameter (i, i) indicative of a force exerted by the electromagnet to calculate an estimated force (F), to compare the force reference with the estimated force, and to control the amplifier.
