Control strategies for a subsea multiphase electric pump system

This thesis presents the design, simulation and real time implementation of control strategies of a subsea multiphase electric pump system, which consists of a pair of piston type pumps, a permanent magnet linear synchronous motor (PLSM) , a voltage source inverter and a control unit. The pump is required to operate efficiently and effectively for pure oil, pure gas, and for a mixture of the two. [Continues.
