Autonomous craft controller system for landing craft air cushioned vehicle
First Claim
1. An autonomous craft controller system for automated control of operation of a landing craft air-cushioned vehicle, said automated system comprising:
- (a) a command processor for receiving and processing multiple inputs relating to vehicle heading, location and velocity and, in response thereto, producing multiple outputs relating to vehicle acceleration and vehicle heading, velocity and position error;
(b) a bow thruster controller for receiving and processing as inputs some of the multiple outputs from said command processor and, in response thereto, producing a bow thruster command output;
(c) a prop pitch controller for receiving and processing as inputs some of the multiple outputs from said command processor and, in response thereto, producing port and starboard prop pitch command outputs; and
(d) a rudder controller for receiving and processing as inputs some of the outputs from said command processor and outputs from said prop pitch controller and, in response thereto, producing a rudder command output.

Abstract
An autonomous craft controller system for automated control of operation of landing craft air-cushioned vehicle includes a command processor, a bow thruster controller, a prop pitch controller, and a rudder controller. The command processor receives and processes multiple inputs relating to vehicle heading, location and velocity and, in response thereto, produces multiple outputs relating to vehicle acceleration and vehicle heading, velocity and position error. The bow thruster controller receives and processes as inputs some of the multiple outputs from the command processor and, in response thereto, produces a bow thruster command output. The prop pitch controller receives and processes as inputs some of the multiple outputs from the command processor and, in response thereto, produces port and starboard prop pitch command outputs. The rudder controller receives and processes as inputs some of the outputs from the command processor and outputs from the prop pitch controller and, in response thereto, produces a rudder command output.

16. An autonomous craft controller system for automated control of operation of a landing craft air-cushioned vehicle, said automated system comprising:
-
(a) a command processor for receiving and processing multiple inputs which include vehicle waypoint heading, and X, Y positions, and vehicle heading rate, X, Y positions and velocities, and, in response thereto, producing multiple outputs which include heading rate error, heading acceleration, lateral velocity error, lateral acceleration, longitudinal velocity error, longitudinal acceleration and longitudinal position error; (b) a bow thruster controller for receiving and processing as inputs said heading rate error output, heading acceleration output, lateral velocity error output and lateral acceleration output from said command processor and, in response thereto, producing a bow thruster command output; (c) a prop pitch controller for receiving and processing as inputs said heading rate error output, heading acceleration output, lateral velocity error output, lateral acceleration output, longitudinal velocity error output, longitudinal acceleration output and longitudinal position error output from said command processor and, in response thereto, producing port and starboard prop pitch command outputs; and (d) a rudder controller for receiving and processing as inputs said heading rate error output, heading acceleration output, lateral velocity error output and lateral acceleration output from said command processor and said starboard prop pitch command and port prop pitch command outputs from said prop pitch controller and, in response thereto, producing a rudder command output.
