PMSM Simulation Model Based on Mathematical Modeling with Dual-Loop PI Control Implementation

To achieve adjustable speed control for permanent magnet synchronous motors (PMSM), we need to establish a comprehensive simulation model. This model is constructed based on the mathematical framework of PMSM, implementing dual-loop control strategy through PI controllers - typically involving an outer speed loop and an inner current loop. The controller algorithms utilize proportional-integral calculations to minimize error between reference and feedback signals, enabling precise motor speed regulation to meet target specifications. Through this simulation model, developers can gain deeper insights into motor dynamics and optimize real-world applications. The implementation typically involves mathematical representations of dq-axis transformations, flux linkage equations, and electromagnetic torque calculations. This simulation framework serves as an essential tool for engineers researching and developing PMSM systems, allowing parameter tuning and control strategy validation before physical implementation.
