Marine motor control strategy based on indirect vector control and feedforward compensation

This paper presents a marine motor control strategy based on the combination of indirect vector control and feedforward compensation. Through the torque feedforward link, desired electromagnetic torque is acquired. Assisted with indirect vector control, desired quadrature-axis currents are obtained with respect to the calculated motor torque and given direct-axis current. Then the two currents are substituted into the voltage feedforward link for the purpose of deriving direct-and quadrature-axis voltages for SVPWM implementation. Matlab-based simulated results prove the correctness and validity of the proposed methodology.
