To demonstrate the validity of the direct torque control system for asynchronous motor based on three?level inverter, a subsystem simulation models in the direct torque control system for asynchronous motor were established by means of excellent modular and hierarchical system simulation capability of simulation software Saber. The subsystem models were integrated into a complete system model according to the theory of direct torque control. The simulation experiment was carried out with the system simulation model. The result of simulation analysis shows that the system simulation model is effective,and the direct torque control system has excellent dynamic response performance.
