Aiming at the control problem of asynchronous propulsion motor in electric propulsion ship, simulation models of the asynchronous motor vector control, direct torque control, and reciprocal power-fed motor platform is built with MATLAB. Moreover, asynchronous electric dynamometer is used to simulate the ship propeller load characteristic, so as to provide the propulsion motor with propeller load. Finally, a physical system including frequency converter, PLC, PC WINCC and so on is built under laboratory conditions. The simulation and experiment results can verify the effectiveness of this approach.
