Implementação de controle de conjugado de motor a relutância variável com vistas a sua aplicação em tração elétrica

Abstract

This work presents the implementation of a control strategy for the application in a variable reluctance motor, considering its use in electric traction. For this, the resources of the MATLAB / SIMULINK / SIMPOWERSYSTEM® software were used. A soft-type current hysteresis control system and torque control was designed, focusing on the motor drive at the θoff angle of each phase. The main objective of this strategy was to reduce torque oscillation, since it causes problems in the engine's operation, such as vibrations, noise and losses in the machine's power. In this work, several current references were used and a vast demonstration of the equations that govern both the operation of the variable reluctance motor, as well as the current and torque control evidenced. With the results obtained, it becomes possible to assess the feasibility of this resource for applications that require high performance and efficiency, such as electric traction.
