Simulation of induction motor direct torque control system for marine electric propulsion

摘要

In this paper, the basic structure and characteristics of the marine electric propulsion system are introduced, The control principle of direct torque control system of induction motor is analyzed. The key points are the composition and realization of direct torque control system, A model of direct torque control (DTC) of induction motor drives was established, and dynamic simulation research was performed in Saber environment. Simulation results show the validity of the model.
