Abstract
A system for testing a vessel control system includes sensors on board the vessel to send one or more sensor signals over a signal line to the control system; command input devices on board the vessel to send one or more of desired position, course, velocity, etc. over a command signal line to the control system; an algorithm in the control system to compute control signals to based on sensor data, communication lines for sending of one or more simulated signals and/or simulated command signals from a remote test laboratory to the control system; and a simulator including an algorithm for the simulation of the new dynamic state of a vessel model based on a previous state, the control signals, and the dynamic parameters of the vessel. The control system continues to compute the control signals to achieve at least one of desired position, course, velocity, etc. based on real and/or simulated sensor signals and real and/or simulated command signals.
