1. A ship propulsion system for a ship including an electrical on-board power supply network, comprising:
- a control lever arrangement, including a control lever, adapted to emit a control lever signal corresponding to the position of the control lever, a source for production of electrical power, an electrical actuating device, including a power input, a power output and a control input, wherein the power input is connected to the source;
an electric propeller motor, adapted to drive a ship'"'"'s propeller and connected to the power output of the actuating device;
a rotation speed sensor, adapted to emit a rotation speed signal corresponding to the rotation speed of the ship'"'"'s propeller;
a regulator device, including a regulator output, a nominal value input and an actual value input, wherein the control lever signal is fed into the nominal value input and the rotation speed signal is fed into the actual value input, and wherein the regulator output is connected to the control input of the actuating device; and
filter means for suppressing rates of change of instantaneous values of the electrical power, emitted by the actuating device to the propeller motor, which cause adverse effects on the ship operation.

Abstract
A ship propulsion system includes a ship electrical system and an electric propulsion system that is supplied with power from the electrical system, and which is equipped with a cascade control for the propeller motor. The rotational speed of the propeller motor is preset by a higher-order controller whose command variable is issued by the throttle lever. Filters means are provided for suppressing impairments to the ship'"'"'s operation that result due to the high dynamics of the propulsion system.
