Problems solved by technology

During the track tracking control process, if the track controller, rudder angle controller, and control signal receiving device have step-type or slope-type faults, or the steering gear has a stuck-type fault, the course of the untethered deep submersible cannot be achieved. Accurate control, thus affecting the effect of track tracking control

Description

technical field [0001] The invention relates to a cableless deep submersible track tracking control system, which belongs to the technical field of cableless deep submersible track tracking control and fault detection. At the same time, the invention discloses its fault detection method. Background technique [0002] The deep submersible is an active deep diving device with underwater observation and operation capabilities, and is mainly used to perform tasks such as underwater investigation, seabed exploration, seabed development and salvage, and lifesaving. Compared with cabled deep submersibles, untethered deep submersibles have stronger maneuverability and are more convenient to perform mine countermeasures, submarine tracking in coastal areas, and intelligence, surveillance and reconnaissance tasks. The track tracking control of the cable-free deep submersible refers to making the track of the cable-free deep submersible follow the set trajectory through the steering i...
