Synchronous Motor Sliding Mode Position Tracking Control Technology in Complex Environment

With high stability, power density, simple structure, and small size, permanent magnet synchronous motor (PMSM) exhibit very high application value in wind power generation, rail transportation, and manufacturing processes. The strong robustness and anti-interference ability of sliding mode control (SMC) make it the most frequently used control method in motor control systems. Fractional-order sliding mode control (FOSMC) not only combines the advantages of both fractional-order calculus (FOC) and SMC, but also serves as an important aspect of fractional-order research, providing a promising direction for the optimization and study of SMC. Therefore, this study is based on fractional-order SMC, starting from the theoretical perspective of the PMSM control model. By elaborating on fractional-order non-singular terminal SMC and fractional-order adaptive sliding mode position tracking control, the control of PMSM is explored.
