The Design and Implementation of a BLDC Motor Drive with DTC
This paper presents a brushless DC (BLDC) motor drive with direct torque control (DTC).The detailed hardware and software design are analyzed and designed. The performance of the BLDC employing DTC is compared with that of BLDC utilizing PWM current control. A prototype of BLDC motor drive based on the DSP controller with DTC control is implemented and validated by the exhibition of waveforms measurement for currents, torque, flux linkage, and speed. The experimental results not only verify the feasibility of designed system but also demonstrate that BLDC with DTC control has superior characteristics than that with PWM current control.
