Resource Overview

A simulation model for permanent magnet synchronous motor using dual closed-loop control of current and speed with implementation of PI controllers and SVPWM modulation.

Detailed Documentation

This simulation model employs dual closed-loop control of current and speed specifically designed for permanent magnet synchronous motors (PMSM). The operating principle of PMSM is based on the alternating magnetic interaction between rotor permanent magnets and stator electromagnetic poles, which generates rotational torque. In this model, the motor's operational state is regulated through current and speed controllers, typically implemented using PI control algorithms for precise tracking of reference values. The model incorporates space vector pulse width modulation (SVPWM) technique for efficient inverter control. Key performance indicators including motor efficiency, power output, and response speed can be evaluated and optimized through parameter tuning in the simulation environment. The implementation includes mathematical modeling of electromagnetic torque equations and flux linkage characteristics. This simulation model finds widespread applications across various industrial sectors such as wind power generation systems and new energy vehicles, enabling system performance validation and control strategy development before physical implementation.
