The line acquisition control uses a line-of-sight guidance law, and acquires the line within 100m.
Using line-of-sight guidance principles, navigation trajectories could be calculated in real-time providing autonomous navigation between user designated waypoints.
In the paper, an autopilot system composed of sliding mode controller and line-of-sight guidance technique are adopted to navigate the ship in random waves by altering the rudder deflection.
First, a nonlinear controller adopting Lyapunov's direct method and backstepping technique is proposed for under-actuated AUV, based on the Line-of-Sight guidance built in a moving Frenet Serret frame.
First, an improved 3D line-of-sight guidance law that makes full use of the essentially equivalent coordinate transformation is derived to transform 3D path following position errors into controlled guidance speeds, which also reduces the path following system form second-order to first-order.
In particular, we use a line-of-sight (LOS) guidance law as the reference angle for the head link.
This design method is then applied for the missile's command to line-of-sight (CLOS) guidance law design.
Specifically, a robust individual path following controller is developed based on a line-of-sight (LOS) guidance law and a reduced-order extended state observer (ESO).
This paper presents a novel predictor-based line-of-sight (PLOS) guidance law for the path following of underactuated marine surface vehicles.
The track-keeping mission is achieved through a sequence of course-changing maneuvers and the reference heading is computed with the line-of-sight (LOS) guidance law.
