HIGH-SPEED ELECTRIC DRIVE OF A MARINE AUTONOMOUS PROFILER WITH ADJUSTABLE BUOYANCY
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.
