Desenvolvimento de um Simulador para uma Máquina de Relutância Variável tipo 6/4 Projetada em Laboratório

Abstract

This paper presents the development of a switched reluctance machine (SRM) 6/4 simulator. The machine was developed by teachers and students of the Federal University of Ceará. Thus, came the need to design a simulator that considers the intrinsic parameters and non-linearities of this machine. For this, the mathematical modeling of the machine, the characterization of the mechanical parameters and the identification of the inductance profile were performed. In addition, the drive circuit was developed based on an asymmetric half-bridge converter, considering different drive logic. It was also envisaged the application of different loads in the SRM, being possible to operate it as a primary machine of a direct current (DC) generator or in phase lack. In order to evaluate the simulator implemented in the laboratory test bench, a speed controller was developed, which is test-ed in the simulator and in the bench, in the condition of load application in the DC generator and in phase lack. The experimental results of speed remained within the values observed in the simulator, while the reference current generated by the controller of the simulator showed close values when operating around the plant identification point. The data comparison proved the simulator efficiency.
