Permanent Magnet Synchronous Motor Vector Control System

This article presents the author's self-developed vector control system for permanent magnet synchronous motors utilizing space vector pulse width modulation (SVPWM) control methodology. The system achieves high-efficiency and stable motor operation through an innovative control strategy implementation. The author emphasizes the system's stability and reliability, demonstrating robust performance under various operating conditions. The control algorithm incorporates current loop regulation and field-oriented control principles to maintain precise torque and flux control. The implementation likely involves Clarke/Park transformations for coordinate system conversions and sector identification logic for SVPWM waveform generation. Additionally, the author discusses future development directions, including potential enhancements for performance optimization and control algorithm refinements to adapt to evolving market requirements. Potential improvements may involve adaptive PI tuning methods, sensorless control techniques, or harmonic suppression algorithms for better dynamic response and reduced torque ripple.
