Modeling and Simulation of PMSM DTC System Based on the Speed Sensorless

摘要：

The permanent magnet synchronous motor (PMSM) with its high efficiency, high power factor, small volume and advantage of saving electricity in many areas, has been widely used. The paper mainly analyses PMSM direct torque control (DTC) system, and estimates the speed based on speed sensorless control system, which based on the angle of speed estimation method of the motor rotor flux vector. Use Simulink tool in MATLAB to design and realize the control system simulation, and the simulation results are analyzed. Simulation results show the correctness and feasibility of the speed observation algorithm.
