Terminal weight and constraint design for wave energy converter economic model predictive control problems

International Journal of Robust and Nonlinear Control, Volume 35, Issue 7, Page 2694-2716, 10 May 2025.
Abstract The wave energy converter (WEC) control problem aims to make the best use of wave excitation to maximize energy capture and ensure safe operation across a broad range of sea states. This falls into the recently developed economic model predictive control (EMPC) framework, subject to wave excitation being treated as a predictable additive ...

Simulation and Experimental Study of Hydraulic Cylinder in Oscillating Float-Type Wave Energy Converter

Polish Maritime Research, 2020
Hydraulic cylinders play a vital role in the energy output (PTO) system of an oscillating float-type wave energy converter, whose function is to convert the mechanical energy captured by the float from the waves into hydraulic energy.

Evaluating Vehicle‐Borne and Person‐Worn Spray Technologies to Deliver Target Decontaminant Doses to Urban Surfaces for Biological Remediation

Remediation Journal, Volume 35, Issue 2, Spring 2025.
ABSTRACT The remediation of urban infrastructure contaminated with an environmentally persistent pathogen requires a large proportion of surfaces to be treated with liquid‐based biocides. Critical to this wide area decontamination effort, will be logistically viable approaches that apply target quantities of formulation to these surfaces while ensuring

Control‐Oriented Modelling and Adaptive Parameter Estimation for Hybrid Wind‐Wave Energy Systems

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
Different with the traditional hybrid wind‐wave energy system models that are established by using the boundary element method (BEM), devoting to understanding the hydrodynamic responses and performance analysis. This paper proposes a control‐oriented model of the hybrid wind‐wave energy system with the coupled aero‐hydro‐mooring dynamics. The obtained

Are We Up to the Best Practices in Forage and Grassland Precision Harvest? A Review

Grass and Forage Science, Volume 80, Issue 1, January-March 2025.
ABSTRACT Grassland and forage crops are a domain where the application of precision agriculture techniques has been less intensive so far, compared to grain crops. This is especially evident in the case of variable yield assessment, the step that prompts the adoption of precision management techniques once farmers are faced by unexpectedly high yield ...

Optimization of wind‐wave hybrid system based on wind‐wave coupling model

IET Renewable Power Generation, Volume 18, Issue 8, Page 1407-1427, 8 June 2024.
This study proposes an optimization method based on a wind‐wave coupling model, and takes a new wind‐wave hybrid system as an example for verification and analysis. The results show that the non‐parametric prediction model established in this paper has high accuracy and is used with the NSGA‐II optimization algorithm to effectively improve the wind ...
