Critical Review on Robust Speed Control Techniques for Permanent Magnet Synchronous Motor (PMSM) Speed Regulation

The permanent magnet synchronous motor (PMSM) is a highly efficient energy saving machine. Due to its simple structural characteristics, good heat radiation capability, and high efficiency, PMSMs are gradually replacing AC induction motors in many industrial applications. PMSM has nonlinear system lies on parameters that differ over time with complex high-class dynamics. To achieve the excessive performance operation of PMSM, it essentially needs speed controller for providing accurate tracking, slight overshoot, robust disturbance repulsion. Therefore, this article provides an overview different control techniques reviews implementation controller. In view uncertainty factors, such as parameter perturbation load disturbance, H? strategy mainly reviewed based traditional techniques, i.e., sliding mode (SMC), current Hamilton–Jacobi Inequality (HJI) theory. Based comparative analysis, review simplifies development trend technologies used regulation system.
