Vector Control of PMSM Based on PI Regulator

In this paper, we provide a detailed explanation of the construction process for a simulation model of an interior permanent magnet synchronous motor (PMSM) vector control system. We discuss various modules of the system simulation model, including the establishment of the system simulation framework and parameter configuration procedures. From an implementation perspective, the model typically includes Park/Clarke transformation blocks, space vector pulse width modulation (SVPWM) generation, and PI regulator modules for current and speed control loops. Additionally, we explore the advantages of applying PMSM vector control systems in simulation models and address potential challenges along with corresponding solutions in practical applications. Through this comprehensive discussion, readers will gain a better understanding of the simulation model for interior PMSM vector control systems, thereby providing guidance and assistance for real-world implementations. The simulation typically involves configuring motor parameters such as stator resistance, d-q axis inductances, and flux linkage, while the control algorithm implements field-oriented control through coordinate transformations and regulator tuning.
