System and method for hovercraft docking control based on laser range finder

The invention discloses a system and method for hovercraft docking control based on a laser range finder. The system comprises a compass, the laser range finder, a comparator, a controller, an air rudder and a side air door. The compass collects and transmits a course angle of the current moment of a hovercraft to the comparator, and the laser range finder collects and transmits left-right distances of the current moment of the hovercraft to the comparator; the comparator makes a comparison on the received course angle and an instruction course angle to obtain course deviation, compares the received left-right distances to obtain positional deviation, and transmits the course deviation and the positional deviation to the controller. The controller comprises a course controller and a position sidesway controller, the course controller outputs rudder angle instructions to the air rudder according to the received course deviation, the rudder angle of the air rudder is adjusted, and the position sidesway controller outputs side air door opening and closing instructions to the side air door according to the received positional deviation to control the opening and closing of the side air door. According to the system and method for hovercraft docking control based on the laser range finder, the operating level and sailing stability can be improved.
