Advanced Control of Dual Three-Phase PMSMs: Deadbeat Prediction and Sliding Mode Strategies

With the rapid development of new energy technologies and the automation industry, the demand for high-efficiency, high-precision motor control systems continues to grow. Multiphase motors—particularly Dual Three-Phase Permanent Magnet Synchronous Motors (DTP-PMSMs)—are increasingly used in key sectors such as new energy vehicles, ship propulsion, and industrial automation, due to their high power density, low torque ripple, and excellent fault-tolerant performance. However, the complex structure of these motor systems, along with numerous control parameters, strong coupling effects, and significant harmonic influences, makes traditional control strategies insufficient to meet the high dynamic performance and robustness required by modern multiphase motor applications. As a result, research and development of advanced high-performance control algorithms have become essential to improving the overall performance of DTP-PMSM systems.
