The rapid development of renewable energy sources and electricity storage technologies is
further driving the change and evolution of traditional energy systems. The aim is to …

This paper addresses the periodic position tracking and load force disturbance rejection in
linear permanent magnet synchronous motors (LPMSM). Periodic position tracking is a …

The traditional PI controller has limited ability to suppress magnetic field noise with high
power spectral density and specific frequencies, leading to degradation in …

In this work, stable H∞ controller design problem for linear time-invariant single-input single-
output plants, which have infinitely many open-right-half-plane zeros and possibly infinitely …

This paper presents a methodology for the synthesis of multiple resonant controllers in the
voltage regulation loop of uninterruptible power supplies (UPSs) operating in parallel with …

Repetitive controller (RC) and multiple quasi-resonant controllers (MQ-RSC), both based on
internal model principle, are widely used in ac voltage/current control of single-phase …

A strategy for the implementation of the output impedance in single‐phase inverters
connected in parallel with droop control for uninterruptible power supply applications is …

A new method to construct a discrete-time variable-structure repetitive controller for a class
of linear systems perturbed by multiple-period exogenous signals is presented. The …

In this research article, the proportional-resonant controllers (PR) are introduced to fulfil the
increased demand for controllers aiming at the tracking and/or rejection of periodic signals …

In this paper, a three-level reduced switch converter is proposed for the online three-phase
uninterruptible power supplies (UPS). The three-level reduced switch converter has only …
