- Abstract
The design requirements of brushless DC (BLDC) motor control system are on the increase high with the continuously broaden application fields of it. This paper presents the direct torque control(DTC) drive scheme for BLDC motor. The rationale of DTC for BLDC motor is analyzed and torque error is directly used to control the inverter states. The magnitude and phase angle of stator flux linkage vector are deduced under the - axis stationary reference frame. The control algorithm of stator flux linkage and torque is hysteresis control, then the results and flux linkage regulate the inverter. MATLAB simulation results indicate that DTC scheme for BLDC motor has faster speed of torque response and better performance, achieve the purpose.
