Abstract
A system and method are provided for controlling movement of a marine vessel. An operator controllable device outputs a signal that is representative of an operator-desired rate of position change of the vessel about or along an axis. A sensor outputs a signal that is representative of a sensed actual rate of position change of the vessel about or along the axis. A rate of position change controller outputs a rate of position change command based upon the difference between the desired rate of position change and the sensed rate of position change. A vessel coordination controller controls movement of the vessel based upon the rate of position change command.
Claims17
A system for controlling movement of a marine vessel, the system comprising:
- a operator controllable device having an output that is representative of a operator-desired rate of position change of the vessel about or along an axis;
- a sensor having an output that is representative of a sensed actual rate of position change of the vessel about or along the axis;
- a rate of position change controller outputting a rate of position change command based upon the difference between the desired rate of position change and the sensed actual rate of position change;
- and
- a vessel coordination controller controlling movement of the vessel based upon the rate of position change command;
- wherein the rate of position change controller is configured to interpret a lack of movement of the operator controllable device to be a request for active suppression of position change rather than as a request for no position change.
A method for controlling movement of a marine vessel, the method comprising the steps of:
- operating a manually controllable device to detect a operator-desired rate of position change of the vessel about or along an axis;
- sensing an actual rate of position change of the vessel about or along the axis;
- outputting a rate of position change command based upon the difference between the operator-desired rate of position change and the sensed actual rate of position change;
- controlling movement of the vessel based upon the rate of position change command;
- wherein the rate of position change controller is configured to interpret a lack of movement of the operator controllable device to be a request for active suppression of position change rather than as a request for no position change.
A system for controlling movement of a marine vessel about a yaw axis, the system comprising:
- a joystick having an output that is representative of a desired yaw change rate;
- a sensor having an output that is representative of a sensed actual yaw rate of the marine vessel;
- a yaw rate controller outputting a yaw rate command based upon the difference between the desired yaw change rate and the sensed actual yaw rate;
- a vessel coordination controller outputting an actuation command based upon the yaw rate command;
- and
- an actuator controlling movement of the marine vessel based upon the yaw rate command;
- wherein the rate of position change controller is configured to interpret a lack of movement of the operator controllable device to be a request for active suppression of position change rather than as a request for no position change.
