| Abstract: | Adopting rotor field-oriented vector control methods,through which make the sta- tor and the rotor magnetmotive forces can be kept orthogonal all along during operation of the BLDCM,combining hysteresis current modulation's current control advantage and space voltage vector modulation's torque ripple attenuation advantage,then designing a sort of BLDCM hyster- esis current SVPWM control method.The experiment results indicate that this method is more effective in the brushless direct current motor's low speed torque ripple attenuation,and its more effective in improvifig system dynamic performance. |
