Abstract
Direct torque control is the most excellent control technology for induction-motor at present.Digital signal processor with high speed arithmetic and logic operation is the base for its digital realization.In this paper,it introduces the principle of direct torque control and the character of TMS320LF2407 digital signal processor.At the same time,it gives the software and hardware design of direct torque control system for asynchronous-motor based on TMS320LF2407 DSP.With experimentation and simulation,it proves the good character of direct torque control.
