Permanent Magnet Synchronous Motor Main Program

The Mysmo.mdl file serves as the main program for Permanent Magnet Synchronous Motor (PMSM) control, implementing both speed-sensor-based startup operation and sensorless operation algorithms. The SMOmodel.m file contains an enhanced sliding mode observer model that estimates back-electromotive force (back-EMF) in PMSM systems using advanced signal processing techniques. The PFCDCM0hm5 model utilizes a 0.5H inductor to convert 220V AC power to 400V DC output with discontinuous current mode operation. Since this is a simulation model, hardware implementation would require additional components including voltage sampling circuits and input voltage zero-crossing detection circuitry for proper synchronization. The PFCCM320percent98k50 model employs a 5H inductor for AC-DC conversion, transforming 220V AC input to 320V DC output with continuous current flow. This configuration achieves a power factor of 0.98 using a 50kHz switching frequency control algorithm. The PFCCM400percent97k50.mdl model also uses a 5H inductor to convert 220V AC to 400V DC with continuous current operation, achieving a power factor of 0.97 at 50kHz switching frequency. These simulation models incorporate detailed implementation aspects and explanatory enhancements to better communicate their core technical concepts and control methodologies.
