Abstract: A digital implementation method of discrete space vector modulation direct torque control (DSVMDTC) system of induction motors was presented. The software and hardware design scheme of DTC driving system using the TMS320F2812 was investigated in details. The experiment results show that torque ripple was significantly reduced, the wareform of current and flux linkage were improved effectively and the technology of DSVM control keep the advantage of fast torque response of DTC.
