Design and Comparison Direct Torque Control Techniques for Induction Motors

In this paper a comparison of two significant control methods of induction motor are presented. The first one is a classical Direct Torque and Flux Control (DTC) and is compared with a scheme, which uses Space Vector Modulator (DTC-SVM). A comparison in respect to dynamic and steady state performance of the drives is presented. The methods are compared in order to perform the demands from Adjustable Speed Drive (ASD). Simulation and experimental results for both methods are shown
