Multiprocessor based current control of brushless motor

For the current control of brushless motor, it is possible to generate the reference current waveforms by a microcomputer. But, with a single microprocessor, those reference current waveforms are not produced in smooth shapes because of computation speed. To solve this problem an attempt hag been made in this paper to use two processors, where the additional processor is to transform the current space vectors. This approach does not increase the complexity of the design considerably compared to the cage of using a single processor.
