Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0026] A structure of the field weakening control method of the built-in permanent magnet synchronous motor based on the torque feedforward control technology of the present invention is as follows figure 1 shown. The software algorithm part includes stator flux adjustment module, current data table, current regulator, pulse width modulation, Transformation and Park Transformation. The hardware part includes uncontrolled rectifier bridge and inverter.
[0027] The stator flux linkage adjustment module calculates a suitable stator flux linkage given value as an output according to the input torque given value, DC bus voltage, motor speed and modulation coefficient.
[0028] The current data table includes two two-dimensional tables. Each table has two input variables: torque reference and stator flux reference. The outputs of the two tables are the...
