Embodiment Construction
[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0032] Such as figure 1 As shown, the present invention takes the permanent magnet synchronous motor vector control system as an example. The permanent magnet synchronous motor vector control system includes a position sensor 1, a permanent magnet synchronous motor (PMSM) 2, a speed calculation module 3, a speed loop PI regulator 4, a current Sensor 5 , summation module 6 , coordinate transformation module 7 , current loop PI regulator 8 , space vector pulse width modulation (SVPWM) module 9 , current loop PI regulator 10 and inverter 11 . Among them, the position sensor 1, the speed calculation module 3 and the speed loop PI regulator 4 form a speed loop; the coordinate transformation module 7 and the current loop PI regulator 8 form a q-axis current loop; the coordinate transformation module 7 and the current loop PI regulator 10 form a The d-axis ...
