A microstructure flux profiler control system design

A microstructure flux profiler (MFP) which uses variation of its buoyancy to maintain the speed required for data logging is detailed. The variation of buoyancy to control speed is uncommon among profilers, and the autonomous operation of this device allows a much greater degree of flexibility in the data collection. The complete development of the control system, from modeling through simulation and control system design to commissioning, is examined, and the performance is reviewed
