Vector Control of PMSM Applied in Ship Electric Propulsion System based on dsPIC

Taking the three-phase permanent magnet synchronous motor (PMSM) applied in ship electric propulsion system as an example, this paper discusses the mathematical model of the PMSM and the vector control principle and describes the algorithm of the space vector pulse width modulation (SVPWM). Finally, the SVPWM control model for PMSM is established in Matlab/Simulink and the experimental setup is built using dsPIC. The simulation and experimental results both verify the correctness and effectiveness of the proposed method.
