Direct data-driven LPV control of nonlinear systems: An experimental result

IFAC-PapersOnLine, 2023
We demonstrate that direct data-driven control of nonlinear systems can be successfully accomplished via a behavioral approach that builds on a Linear Parameter-Varying (LPV) system concept. An LPV data-driven representation is used as a surrogate LPV form of the data-driven representation of the original nonlinear system.

Two-Degree-of-Freedom Controller Design Based on a Data-Driven Estimation Approach

IEEE Access, 2022
Data-driven control design is a method to create and tune controllers directly from the initial experimental data without a mathematical model to be controlled. Tracking and disturbance suppression are necessary to control real systems.

pyvrft: A Python package for the Virtual Reference Feedback Tuning, a direct data-driven control method

SoftwareX, 2020
In this paper, the pyvrft, a Python package for the data-driven control method known as Virtual Reference Feedback Tuning (VRFT), is presented. Virtual Reference Feedback Tuning is a control design technique that does not use a mathematical model from ...

Direct Sampling for Spatially Variable Extreme Event Generation in Resampling‐Based Stochastic Weather Generators

Journal of Advances in Modeling Earth Systems, 2023
Resampling‐based weather generators simulate new time series of weather variables by reordering the observed values such that the statistics of the simulated data are consistent with the observed ones.

Direct data‐driven design of switching controllers

International Journal of Robust and Nonlinear Control, 2019
SummarySwitching linear models can be used to represent the behavior of hybrid, time‐varying, and nonlinear systems, while generally providing a satisfactory trade‐off between accuracy and complexity. Although several control design techniques are available for such models, the effect of modeling errors on the closed‐loop performance has not been ...

Time Delay of Wide Area Damping Control in Urban Power Grid: Model-Based Analysis and Data-Driven Compensation

Frontiers in Energy Research, 2022
Due to the rapid development of economies, large urban cities consume an increasing amount of energy and have a higher requirement for power quality. Voltage source converter based high voltage direct current (VSC-HVDC) is a promising device to transmit ...

The Impact of Starbursts on the Circumgalactic Medium [PDF]

, 2013
We present a study exploring the impact of a starburst on the properties of the surrounding circum-galactic medium (CGM): gas located beyond the galaxy's stellar body and extending out to the virial radius (200 kpc). We obtained ultraviolet spectroscopic

Fighting viral infections and virus-driven tumors with cytotoxic CD4+ T cells [PDF]

, 2017
CD4+ T cells have been and are still largely regarded as the orchestrators of immune responses, being able to differentiate into distinct T helper cell populations based on differentiation signals, transcription factor expression, cytokine secretion, and
