Abstract :
According to the characteristic of permanent magnet synchronous motor (PMSM), this paper realized the simulation of its servo system based on the power system toolbox of Matlab/Simulink. Then this paper proposed a full-digital PMSM servo system based on digital signal processor (DSP) and complex programmable logical device (CPLD), which includes testing modules for phase current, rotor position and rotor speed, and modulation of trigger pulse. Based on the field-oriented control method, the PMSM speed adjustment through DSP C language was realized. The result indicates that, this system has prompt dynamic response and well steady-state behavior
