Abstract:

   A high-speed electric drive designed for operation in the buoyancy control system of an autonomous marine profiler is proposed and investigated. Its main feature is the use in the control  loop of a linear electric direct current machine, working together  with  a PID controller.  Application   of this approach  will  increase the speed of the buoyancy engine, increase the rate of profiling and, on this basis, significantly reduce the time  of measurements of the thermohaline parameters of the ocean  environment with  an  allowable accuracy.

Keywords:  profile measurements, controlled profiler,  ocean  environment, buoyancy engine,  linear electric machine, electric drive, mathematical model.
