Software implementation of a rotor flux oriented vector controlled AC drive without an external modulator

In this paper, the software implementation of a rotor flux-oriented current vector-controlled induction motor drive is discussed. The control system and the modulator are realised using a general purpose Motorola 68HC16Z1 single-chip microcontroller . A new space vector modulation implementation for HC16-family microcontrollers is introduced. Some experimental measurements are also shown.
