Abstract: Techniques are disclosed for systems and methods to provide proactive directional control for a mobile structure. A proactive directional control system may include a logic device, a memory, one or more sensors, one or more actuators/controllers, and modules to interface with users, sensors, actuators, and/or other modules of a mobile structure. The logic device is adapted to determine a steering angle disturbance estimate based on environmental conditions associated with the mobile structure, and the steering angle disturbance estimate is used to adjust a directional control signal provided to an actuator of the mobile structure. The logic device may also be adapted to receive directional data about a mobile structure and determine nominal vehicle feedback from the directional data, which may be used to adjust and/or stabilize the directional control signal provided to the actuator.

Abstract: Autopilot systems and related techniques are provided to improve the ability of mobile structures to maintain a desired reference path (e.g., to keep a desired track and/or to follow a desired contour). In various embodiments, a high quality turn rate signal and GPS based signals are used to generate high bandwidth cross track/contour errors and other associated signals. An adaptive controller uses the generated cross track/contour signals to provide robust track keeping and/or contour following in the directional control of a mobile structure. Techniques are also provided for systems and methods to provide directional control for mobile structures.

Abstract: Techniques are disclosed for systems and methods to provide accurate, low lag, and reliable autopilot autorelease in a hydraulic steering system for mobile structures. A hydraulic steering system includes a logic device configured to communicate with an autopilot pump controller, a control surface reference sensor, an orientation sensor, and/or a gyroscope. Control and sensor signals provided by the pump controller and/or the various sensors are used to selectively enable and/or disable an autopilot release signal. The autopilot release signal enables or disables the autopilot pump controller and/or an autopilot pump, or controls the autopilot pump controller to enable or disable the autopilot pump.
