Permanent magnet synchronous motor vector control based on MATLAB/Simulink

This paper presented the mathematical model of permanent magnet synchronous motor (PMSM) and the basic principle and realization of vector control (also called field-oriented control, FOC). The simulation model of PMSM based on speed and current double closed loop using vector control in the MATLAB/Simulink environment is built and experimentally simulated. The result shows that the vector control system of PMSM has the super characteristics of dynamic response and speed control, effectively verifying the correctness of the “id = 0” control algorithm, and provides a theoretical basis for the analysis, design and debugging of PMSM. Finally, according to the basic idea of space vector pulse width modulation (SVPWM) technology, combined with TI Company's DSP (Digital Signal Processor) TMS320F28035, a complete set of model system in Simulink capable of being built to hardware circuit board drives PMSM with speed adjustment.
