Aiming at the problem of inadequate adaptability of conventional control strategy of electric propulsion system under rough sea conditions, an anti-spin thruster control strategy for marine electric propulsion system was proposed. Firstly, the influence of water entry and exit on thrust and torque of propeller under rough sea condition was analyzed, the anti-spin thruster control strategy with dynamic speed limiting module (anti-spin thruster control strategy #1) and anti-spin thruster control strategy with ventilation identification module ( anti-spin thruster control strategy #2) were proposed, and three kinds of suction effect recognizers were designed in the latter to detect inspiratory effect. Secondly, the propulsion control simulation model was built in Matlab/Simulink environment. Finally, the simulation experiment under rough sea condition was designed to compare the performance between the conventional control strategy and the antispin thruster control strategy. The simulation results show that the anti-spin thruster control strategy with suction identification module has excellent control performance under the rough sea conditions.
