The research and design of asynchronous motor direct torque control system based on DSP

The theory of direct torque control applied in induction motor variable frequency control system is analyzed,and then MATLAB simulation software has been used to establish a DSP-based direct torque control inverter system simulation model,the corresponding simulation result curve;designed a TMS320LF2406 DSP core.The frequency control hardware system test results show that the system has an excellent dynamic and static performance.
