Anti-Saturation Speed Regulation Using Dual-Parameter Sliding Mode Observer for PMSM Servo Systems

Accurate state estimation is essential for designing high-performance permanent magnet synchronous motor servo systems. However, the saturation of system input will severely undermine the consistency between control commands and actual inputs, leading to deviations between observer’s state prediction and actual system state, further deteriorating control performance. To address these issues, this article presents an anti-saturation speed regulation scheme integrating a dual-parameter sliding mod
