Implementation of direct stator flux orientation control on aversatile DSP based system

摘要

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