A control system for a ship

摘要

The control system comprises at least one propulsion unit, a lever (200) by which an operator controls the speed and the direction of the at least one propulsion unit (100), a control circuit (300) controlling the speed and the direction of the at least one propulsion unit (100) based on the control signals received from the lever (200), and a force feedback (220) acting on the lever (200). The system comprises further an algorithm (310) receiving as input signals measured process values (M1) relating to operational parameters of the ship and the at least one propulsion unit (100). The control circuit (300) controls the force feedback (220) by comparing the requested operation received from the lever (200) with safe and/or optimal limits received from the algorithm (310) in order to transfer haptic information through the lever (200) to the operator indicating that the requested operation is beyond safe and/or optimal operational limits of the at least one propulsion unit (100).
