Desenvolvimento de um controle de corrente para a máquina a relutância variável 6x4 operando como motor

Abstract

Switched Reluctance Machines have become competitive when compared to traditional induction motors and permanent magnet motors, especially when operating at variable speed. This is also due to some inherent advantages of the machine such as constructive simplicity, high speed operation without rotor magnets or phases, adaptability to conditions. hostile etc. Given the above, it is essential to investigate the particularities of MRV. Envisioning these needs, this paper presents a contribution to the study of Switched Reluctance Machine driven as a motor, with hysteresis current control. The main objective is to present the motor under various operating conditions, as well as the development of a current controller. Thus, it presents a mathematical model for the Switched Reluctance Motor that uses linear sinusoidal modeling and a computational model for analysis in permanent and transient regime. A phase switching control strategy is also presented by varying the magnetization angle by actuating the upper and lower switches of the Half Bridge asymmetric converter. The detailed description of the asymmetric converter equation via hysteresis and design in SIMULINK is presented and discussed.
