A Review of Model Predictive Direct Speed Control for PMSMs: Classification, Robustness and Comparative Analysis

Permanent magnet synchronous motors (PMSMs) are widely used in high‐performance servo systems and electric transportation, placing higher demands on the dynamic response, steady‐state accuracy and robustness of speed control systems. Model predictive direct speed control (MPDSC), which directly optimizes the rotor speed based on a predictive model, exhibits significantly superior overall performance compared with traditional cascaded controllers. This paper presents a systematic review of MPDSC methods for PMSMs. Within a unified predictive control framework, existing research is categorized into four types: finite control s‐et MPDSC (FCS‐MPDSC), deadbeat‐based MPDSC (DB‐MPDSC), continuous control set MPDSC (CCS‐MPDSC) and explicit MPDSC (EMP‐DSC). Focusing on key problems, representative research works and their improvement strategies are surveyed. After that, the two common issues of weighting factors and robustness are systematically discussed. Furthermore, a comparative analysis of typical methods is conducted to clarify their respective features and application scenarios. Finally, the main challenges and development trends of MPDSC in different terms are discussed. This review aims to provide systematic references and technical guidance for further research and practical applications of MPDSC methods.
