Análise comparativa dos métodos de acionamento de seis passos e controle vetorial aplicados a motores síncronos de ímã permanente

Abstract

This work presents a comparative analysis between the six-step control method and the fieldoriented control method applied to a permanent magnet synchronous motor. The theoretical framework presents the necessary concepts for the development of the work, such as the Park Transform, the state-space model of the permanent magnet synchronous motor, the inverter circuit, and the control methods. For the six-step method, a proportional-integral controller was used for speed control, and for the field-oriented control method, three proportional-integral controllers were used for speed control and direct and quadrature axis currents. The numerical simulation in Matlab is presented, and subsequently, the practical implementation on a benchtop using the STM32F411CEU6 microcontroller. From the analyses, it was possible to observe that the permanent magnet synchronous motor achieved better efficiency when driven by the field-oriented control, with an average difference of approximately 6% compared to the six-step method.
