Integrated Model Predictive Control of Permanent Magnet Synchronous Motor Drive Fed by a 3-Phase Interleaved Boost Converter

Interleaved DC-DC converters are a popular choice due to their benefits of low current ripple, high efficiency, and flexibility. However, in applications such as electric vehicles where the load comprises a motor drive system consisting of another converter, using separate controllers for the converters can result in various issues, such as delays, higher complexity, and increased costs. To overcome these problems, a paper proposes a finite control set model predictive control method that can simultaneously control a 3-phase interleaved boost converter and a permanent magnet synchronous motor drive inverter. The paper suggests writing the governing equations of converters to find the relationship between them and create an integrated control system. The proposed control method's effectiveness is verified through simulation and compared against separate controllers. The results indicate that the proposed approach can achieve superior dynamic and steady-state responses, as well as greater efficiency and reliability.
