Improved DTC Control Strategy of B12 Inverter Fed BLDC Motor Drives Considering Commutation Torque Dips

by Rabiaa Mars, Badii Bouzidi, Bassem El Badsi and Abderrazak Yangui

Advances in Science, Technology and Engineering Systems Journal, Volume 3, Issue 5, Page # 427–438, 2018; DOI: 10.25046/aj030549

Abstract:

In most industrial high-power applications, the brushless DC (BLDC) motor is connected to multi-level inverters specially the three-level NPC inverters (B12). Torque ripple is a critical issue in BLDC motor drives. Accordingly, minimizing the ripple produced in the torque is necessary to enhance the BLDC motor drive performances. This paper aims to develop two direct…

Direct Torque Control Strategy Based on the Emulation of Six-Switch Inverter Operation by a Four-Switch Inverter Using an Adaptive Fuzzy Controller

by Salma Charmi, Bassem El Badsi and Abderrazak Yangui

Advances in Science, Technology and Engineering Systems Journal, Volume 3, Issue 2, Page # 346–356, 2018; DOI: 10.25046/aj030237

Abstract:

This paper presents a novel direct torque control (DTC) strategy aimed to four-switch three-phase (FSTP) inverter-fed an interior permanent magnet synchronous machine (IPMSM), using a fuzzy logic toolbox in speed control loop. In fact, the introduced DTC approach is based on the emulation of the operation of the standard six-switch three-phase (SSTP) inverter. This fact…
