Simulation of Vector Control System for Permanent Magnet Synchronous Motor

Permanent Magnet Synchronous Motors (PMSM) are widely used electric machines whose vector control system simulations can employ various control strategies. Here, we implement the id=0 control strategy (which maintains zero d-axis current to maximize torque production) and incorporate a position feedback loop to establish a complete PMSM servo system. The implementation typically involves coordinate transformations (Clark/Park transforms), PI controllers for current and speed regulation, and a position controller for precise angular positioning.

By integrating the position loop, we achieve higher precision control of PMSM, delivering superior performance across various industrial applications. The simulation framework utilizes mathematical models including motor flux equations and mechanical dynamics, with implementation featuring S-function blocks or state-space representations in simulation environments. This control system architecture can be extended to other motor types, significantly improving control accuracy and stability through similar modular implementation approaches involving current regulation, speed control, and position tracking algorithms.
