26. Controle direto de torque para motores de indução - estudo e implementação
DÚ ect torque control is one of the most recent techniques developed for driving induction motors and one of its main advantages is the fast response to electromagnetic torque demanded, allowing the accurate control of motor speed. This control technique is based on the direct ana1ysis of the electromagnetic torque and stator flux errors during the operatio

27. Avaliação de uma nova proposta de controle V/F em malha aberta
This work has the aim of making the performance evaluation of a new open loop speed control method based on the scalar V/f technique for induction motors. The proposed system has been designed intending to minimize speed error through the introduction of the following compensation techniques: Voltage compensation based on the phasor analysis of the input var

28. Implementação digital utilizando DSP do controle por orientação do fluxo do rotor : metodos direto e indireto
In this work the digital implementation of a field rotor flux oriented based control of a squirrel cage induction motor, using a versatile Motorola 56001 digital signal processor is presented. Two methods of orientation are studied: the direct and indirect. The control system contains a PI speed controller. An introductory investigation of the use of Genetic
