TLDR
In this paper, an adaptive frequency domain control algorithm for a PWM switched active power line conditioner (PLC) is discussed, which minimizes harmonic current in the AC line and improves power factor to unity.Abstract:
An adaptive frequency domain control algorithm for a pulse width modulation (PWM) switched active power line conditioner (PLC) is discussed. An active power line conditioner that minimizes harmonic current in the AC line and improves power factor to unity is recommended. A six switch pulse width modulated current source inverter implements the active PLC. Simulation results of the PLC adaptive frequency domain control using the PWM switching algorithm are presented. >read more

Detection is key - Harmonic detection methods for active power filter applications
TL;DR: In this article, a survey of the commonly used methods for harmonic detection in active power filters (APFs) is presented, and a simulation setup that decouples the harmonic detection method from the active filter model and its controllers is proposed.

Switched Controller Synthesis for the Quadratic Stabilisation of a Pair of Unstable Linear Systems
TL;DR: Three stabilising control strategies are discussed: time average control, a variable structure control, and a hybrid feedback control for quadratically stabilising the state trajectory by switching between the two unstable systems.
