英文摘要：

The conventional marine electrical propulsion controller does not fully utilize the dynamic characteristics of the electrical propulsion system.This paper presents hybrid control algorithms which include the capabilities of speed,torque,thruster,and power,and establish the simulation device of marine electrical propulsion based on SIMOTION.Additionally,experimental study of hybrid control for propulsion motors was performed.Comparison study and analysis of propulsion motor speed,torque,and power controllers was achieved.The experimental results show that hybrid control strategies can obtain accurate and smooth speed and torque control as well as lower fluctuations and mechanical wear.
