Abstract
To reduce the torque ripple generated in commutation period of blushless DC motor (BLDCM), the direct torque control (DTC) is used to control BLDCM. The direct torque control principle is analyzed, and a direct torque control scheme for BLDCM without observation of flux linkage is proposed according to the characteristics of BLDCM. In this scheme, a hysteresis-controlled torque loop is adopted, and the voltage space vectors are determined by torque loop output and position of magnetic poles. Simulation and experimental results indicate that the DTC method can significantly reduce the torque ripple of BLDCM and gain perfect dynamic performances.关键词
