Abstract :
A direct stator flux orientation control for induction machines was implemented on a versatile Motorola 56000 digital signal processor (DSP)-based system. Some practical aspects of implementing direct stator flux orientation (DSFO) control, such as parameter identification, flux estimation, and rotor angular velocity estimation, are discussed. Experimental results are presented to show the performance of a DSFO-controlled induction machine drive. Comparison between DSFO and direct rotor flux orientation (DRFO) control shows that DSFO is superior to DRFO in the field-weakening region.<>
