Nonlinear Loads Compensation Using a Shunt Active Power Filter Controlled by Feedforward Neural Networks

open access: yesApplied Sciences, 2021
The shunt active power filter (SAPF) is a widely used tool for compensation of disturbances in three-phase electric power systems. A high number of control methods have been successfully developed, including strategies based on artificial neural networks.

Feedforwarding Under Sampling [PDF]

open access: yesIEEE Transactions on Automatic Control, 2019
The paper deals with stabilization of feedforward multiple cascade dynamics under sampling. It is shown that u -average passivity concepts and Lyapunov methods can be profitably exploited to provide a systematic sampled-data design procedure. The proposed methodology recalls the continuous-time feedforwarding steps and can be applied under the same ...
