Composite Disturbance Compensation for Pmsm Motorized Spindle Systems Using Proportional-Integral and Sliding Mode Observers

Electric spindle systems based on permanent magnet synchronous motors are widely used in high-speed machining and precision manufacturing. However, their speed control performance can be affected by mechanical friction, parameter variations, load fluctuations and unmodelled disturbances, particularly under low-speed re...

Predictive Performance-Based Adaptive PI Control for PMSM Drives

To address the degradation of speed-loop control performance caused by external disturbances and parameter uncertainties, this paper proposes a learning-enhanced predictive PI auto-tuning method for PMSM drives. A discrete-time speed-loop model and a finite-horizon cost function are constructed to balance tracking accu...

Coupled-Transformer Voltage Regulator With Integrated Magnetics and High Power Density

This article proposes a high-power-density flux-split coupled-transformer voltage regulator (FS-CTVR) with improved dynamic response for 48 V data center power supplies. The topology resolves the large winding loss and insufficient dynamic performance of convenitional current Doubler rectifier (CDR) converters. A magne...
