摘要

A simplified direct torque control method is introduced in order to solve difficult situations in flux linkage observation and control of the direct torque control of brush less DC motor. This simplified direct torque control adopts a simplified structure without flux linkage observation and control. To calculate torque of motor in back electromotive force shape function method is simple and effective, which will help realization of the project. The system is simulated with MATLAB/SIMULINK. Results of the experiment show that this simplified method provides better limit to the torque ripple of brush less DC motor comparing with traditional direct torque control method and dynamic response becomes faster.
