Abtact. hi pape peent a pefomance tudy of a Diect oque and Flux Contol (DC) fo a double feed Induction Machine (DFIM). hi method ha become one of the high pefomance contol tategie fo AC machine to povide a vey fat toque and flux contol. he pefomance of DC tongly depend on the quality of the etimated actual tato flux and toque. he imulation eult how the effectivene and the obutne of the popoed method in both dynamic and teady tate epone.

Intoduction he appaition of the field oiented contol (FOC) made induction machine dive a majo candidate in high pefomance motion contol application. Howeve, the complexity of field oiented algoithm led to the development in ecent yea of many tudie to find out diffeent olution fo the induction moto contol having the featue of pecie and quick toque epone. he diect toque contol technique (DC) popoed by: I. akahahi [] and M. Depenbock [2] in the mid eightie ha been ecognized to be a viable olution to achieve thee equiement [, 3]. he cheme, a the name indicate, i the diect contol of toque and tato flux of a dive by invete voltage pace vecto election though a lookup table [2]. 2 JARS.
