Research On Direst Torque Control Of Induction Motor Based On DSP

Following the Vector Control(VC) technique, Direct Torque Control (DTC) of asynchronous motor, which has been developed rapidly in the recent decades, is a new and high-powered AC driving control tech- nique, This idea of DTC is novel, whose structure is simple,and the control strategy is direct as well. DTC is an excellent AC driving control technique,which has high static and dynamic performance and has been successfully applied in many occasions up to now.This paper models and simulates the DTC system in the Matlab/Sim- ulink environment based on the Direct Torque Control theory.In the simulation, three-value torque regulating is considered ,meanwhile, the result is according to the anticipation is provided.In addition, DSP (TMS320F240) of TI Corporation is used as the core-processing chip of the digital control system, and Intelligent Power Module (IPM) is used as the power switch component.Finally,the DTC system is realized with hardware and software by digital signal processor(DSP).
