Vector Control Study Notes: Fundamentals and Advanced Topics of PMSM Motors

This article presents study notes on vector control and summarizes fundamental and advanced knowledge of PMSM motors. In the vector control section, we provide detailed explanations of basic concepts, classification of vector control methods, and their practical applications. The implementation typically involves Clarke and Park transformations for converting three-phase quantities to two-phase rotating reference frames, with proportional-integral (PI) controllers for current regulation. For PMSM fundamentals, we cover motor structure, operating principles, and various control strategies including field-oriented control (FOC) implementations. The advanced topics section discusses optimized control methods such as maximum torque per ampere (MTPA) control, fault diagnosis techniques through current signature analysis, and interconnection methods between motors and related equipment. This comprehensive guide provides complete knowledge of vector control and PMSM technology, offering practical insights with algorithmic explanations and key function descriptions to support your learning journey.
