Abstract


This paper analyzes the permanent magnet synchronous motor (PMSM) mathematical model , based on the depth of the direct torque control of permanent magnet synchronous motor speed control in the application . Built a new switching voltage vector table of permanent magnet synchronous motor control system Matlab simulation model focuses on the extended Kalman filter algorithm principle and the application of this system is constructed based on the extended Kalman filter PMSM torque control system simulation model to achieve a speed sensorless permanent magnet synchronous motor direct torque control application . In this paper, TI has introduced a dedicated microprocessor TMS320LF2407DSP motor to control the core , supplemented by the necessary hardware , completed the design of a complete set of permanent magnet synchronous motor full digital control system, speed sensorless control strategies studied experimentally . Simulation results validate the extended Kalman filter algorithm to speed sensorless motor control is effective and reasonable .
