Robust H8 design for resonant control in a CVCF inverter application over load uncertainties [PDF]

open access: yes, 2020
CVCF (constant voltage, constant frequency) inverters are electronic devices used to supply AC loads from DC storage elements such as batteries or photovoltaic cells. These devices are used to feed different kinds of loads; this uncertainty requires that

Linear Active Disturbance Rejection Control for Nonaffine Strict-Feedback Nonlinear Systems

open access: yesIEEE Access, 2019
This paper presents a linear active disturbance rejection controller (LADRC) for nonaffine nonlinear systems with strict-feedback form. The proposed LADRC results in a closed-loop system with a three-time-scale structure, in which a reduced-order linear ...

Comparison of different repetitive control architectures: synthesis and comparison. Application to VSI Converters [PDF]

open access: yes, 2018
Repetitive control is one of the most used control approaches to deal with periodic references/disturbances. It owes its properties to the inclusion of an internal model in the controller that corresponds to a periodic signal generator.

Closed-Loop Control of a Piezo-Fluidic Amplifier

open access: yes, 2020
Fluidic valves based on the Coand\u{a} effect are increasingly being considered for use in aerodynamic flow control applications. A limiting factor is their variation in switching time, which often precludes their use.
