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.]
A Doctoral Thesis. Submitted in partial fulfilment of the requirements for the award of Doctor of Philosophy at Loughborough University.
