An electrically controlled propulsion system comprises a first electric power system comprising a first electric machine configured to generate a propulsion torque, and a first electric power supply unit electrically connected to the first electric machine, a second electric power system comprising a second electric machine configured to generate a propulsion torque, and a second electric power supply unit electrically connected to the second electric machine, wherein the first and second electric machines are individually controllable, wherein the method comprises obtaining a signal indicative of a first current energy condition of the first electric power supply unit and second current energy condition of the second electric power supply unit; determining a difference between the first current energy condition and the second current energy condition; and controlling the first and second electric machines to reduce a difference between the first and second current energy conditions.
A method for controlling an electrically controlled propulsion system, the electrically controlled propulsion system comprises a first electric power system comprising a first electric machine configured to generate a propulsion torque, and a first electric power supply unit (120) electrically connected to the first electric machine, a second electric power system comprising a second electric machine configured to generate a propulsion torque, and a second electric power supply unit electrically connected to the second electric machine, wherein the first and second electric machines are individually controllable, wherein the method comprises:
A control unit adapted to control an electrically controlled propulsion system, the electrically controlled propulsion system comprising a first electric power system comprising a first electric machine configured to generate a propulsion torque, and a first electric power supply unit electrically connected to the first electric machine, a second electric power system comprising a second electric machine configured to generate a propulsion torque, and a second electric power supply unit electrically connected to the second electric machine, wherein the first and second electric machines are individually controllable using the control unit, wherein the control unit is connectable to the first and second electric power systems and configured to:
An electrically controlled propulsion system comprising a first electric power system comprising a first electric machine configured to generate a propulsion torque, and a first electric power supply unit electrically connected to the first electric machine, a second electric power system comprising a second electric machine configured to generate a propulsion torque, and a second electric power supply unit electrically connected to the second electric machine, and a control unit connected to the first and second electric power systems, wherein the first and second electric machines are individually controllable using the control unit, wherein the control unit being configured to:
