Experimental results for predictive direct torque control for a squirrel cage induction motor

Abstract

The aim of this paper is present the experimental results of predictive control based on model, to improve the dynamic response of three-phase induction machines. In order to perform the model predictive controller, which is used the predictive optimization to achieve the reference. The cost-function is determinate to choose among eight vectors one of them, that is suitable for the requirements. The controller is capable of handle the electromagnetic torque and flux with a simple implementation and adjust easy. To conclude, the results will illustrate the effectiveness of the proposed technique with experiments in practical applications, for a better interpretation was compare with a proportional-integral controller which is possible understand the benefits the predictive control could bring for inductions machines applications.
