Digitized vector control of induction motor with DSP

A field-orientation control system with digital current regulation of induction motor, without external current control loop is proposed. The current control is performed according to an instantaneous voltage equation of a d-q model of the induction motor. The implemented drive is fully digitized, the control algorithm are supported by TMS320C25 digital signal processor (DSP). This control algorithm has been verified by both simulation and experiment and shows a good dynamic performance.<>
