Modelagem matemática e sistema embarcado em DSP/FPGA para acionamento e controle de um GRV 8/6 com estimativa em tempo real das curvas de indutância e conjugado.

Abstract

This work presents a contribution to the study of the Variable Reluctance Machine, presenting the construction of an experimental platform capable of carrying out the reluctance of the machine as a generator, making available all the circuits, components and elements necessary to drive the machine. An algorithm was developed for the drive using DSP / FPGA, both connected to a supervisory system developed specifically for this work. An analysis of MRV inductance curves is presented and a mathematical modeling is developed that allows to reproduce the curves through polynomials for use in simulation tools and in the drive for estimation of the instantaneous and torque inductance. It is also presented a study of the dynamic behavior of the Switched Reluctance Machine operating as a generator in relation to the modification of some operational parameters such as load, speed, excitation voltage, switching angles and lack of phase.
