Estratégia de controle por campo orientado para motores síncronos de relutância com aplicação experimental

Abstract

This paper provides information about indirect field oriented vector control systems for syn chronous reluctance machines. These machines are built from sinusoidally distributed windings in the stator with the rotor made of ferromagnetic material, which results in an efficient motor as it does not contain losses due to rotor currents. The main characteristics of the synchronous reluctance machine are high energy efficiency, low production and maintenance costs, as well as high robustness. In this way, the synchronous reluctance motor can replace the induction motor in industrial applications, which provides energy savings, since synchronous reluctance motors have higher efficiency. The work presents a mathematical model of the synchronous reluctance motor, which is used for the design of controllers and for computer simulations in discrete time. This paper also describes the building and operation of an experimental platform to drive and control the motor. This platform performs measurement acquisitions and signal conditioning that are necessary for the execution of the vector control. The experimental results obtained allow validating the operation of the designed control system.
