Albert Einstein, 400Cidade Universit aria Zeferino Vaz, Campinas, SPABSTRACTThis paper proposes a design and tuning method for acomplex gain CONTROLLER , based on the THREE-PHASE induc-tion motor mathematical model COMPLEX transfer func-tion to be used in the direct torque control at low speedwhich is a problem so far. The design and tuning ofthe COMPLEX gain is done by using the closed loop sys-tem frequency-response function. Experimental resultsare presented to validate the CONTROLLER and operation atlow speed is also : COMPLEX gain CONTROLLER , COMPLEX transferfunction, INDUCTION motor , direct torque trabalho prop oe um m etodo de projeto para umcontrolador de ganho complexo baseado na fun c ao detransfer encia complexa do motor de indu c ao trif asicopara uso no controle direto de torque em
