Implementation of indirect vector control on an integrated digital signal processor-based system

This paper presents an implementation of indirect vector control of inducti on machine on an integrated DSP (Digital Signal Processor) system manufactu red by dSPACE GmbH. The system integrates into a single board the computati onal power of a TMS320C31 DSP with extra peripherals needed in vector contr ol application, and therefore requires minimal hardware development The ind uction machine parameters required for the vector control operation are obt ained through an off line parameters identification using Maximum Likelihoo d estimation technique with a DC voltage source excitation. It is shown thr ough extensive experimental study that the off line identified parameters y ield in a reliable field orientation of the induction machine.
