Improved DC-Link Voltage Sliding Mode Control for Permanent Magnet Synchronous Generator Systems With Three-Phase AC-DC Converters

Mingwei Zhao, Shuo Zhang, Chengning Zhang, Xueping Li et autres

A conventional proportional-integral (PI) controller is commonly used in the dc-link voltage control outer loop of permanent magnet synchronous generator (PMSG) systems; however, it cannot achieve consistent dc-link voltage control performance across the entire operating range, resulting in poor dynamic response. In …
