Abstract:

A method and apparatus for controlling the motion of a cable-driven autonomous moored profiler. The profiler includes one or more buoyant members for buoying the profiler in the fluid, a winch, and a feedback controller for controlling the winch. The winch includes a spool, a device providing for varying rates of turning of the spool, and a flexible cable for winding onto and unwinding from the spool. A first end of the cable is carried by the profiler. The controller monitors an indication of the tension in the cable and controls the device in response thereto.
