Adaptive Sliding-Mode Speed Control Integrated Extended State Observer for Maglev DC Excited Linear Synchronous Motor

IEEE Journal of Emerging and Selected Topics in Power Electronics
Classical speed controller is challenged by nonlinear factors such as discontinuities in the stator iron cores, fluctuations in excitation current, and variations in the suspension air gap, leading to speed fluctuations, especially during low-speed ...

Improved Deadbeat Predictive Current Control With Extended State Observer for Dual Three-Phase PMSMs

IEEE transactions on power electronics
A deadbeat predictive current control (DPCC) method based on extended state observer (ESO) is proposed to improve the control performance of dual three-phase permanent magnet synchronous motors (DTP-PMSMs) under parameter mismatch.

Fast Dynamic Control of Dual-Active-Bridge DC–DC Converter Based on an Adaptive Linear Extended State Observer

IEEE transactions on power electronics
Linear extended state observer (LESO) plays a critical role in ADRC's control performance. However, there exists a tradeoff between disturbance rejection and noise immunity for traditional linear ESO (TLESO).
