Hybrid modeling of an adhesive bonding process, case study : polyphenylene sulfide Universiteit Gent
Adhesive bonding is a joining process used in several industries such as aerospace, automotive, civil construction and manufacturing. Traditionally, the optimization of the parameters for this process is performed by adhesive experts via trial and error which is expensive and time-consuming. Therefore having a process model for optimization purposes is of great interest. In this study, we develop such process model which includes cost, visual ...
Early inner race fault detection on a ball bearing setup using histogram of oriented gradients and wavelet subselection Universiteit Gent
Predictive maintenance is an industrial practice to detect component failure ahead in time and before major damage is done to the system. Bearings are susceptible to such damage phenomena and should be replaced before critical failure, therefore early detection proves important. For wide applicability, these detection methods should work on easily available sensor data and have limited computational complexity. This study presents a method for ...
Scalable recursive state estimation for nonlinear two-dimensional complex networks with switching topology Universiteit Gent
This paper investigates a scalable recursive state estimation method for nonlinear two-dimensional (2-D) stochastic complex networks. In these networks, the switching topology is modelled by random variables generated by the Bernoulli distribution. Considering the Extended Kalman Filter structure, we employ the Taylor series expansion to handle the nonlinear functions in the model. Hence, high-order terms emerging in the linearization process ...
An adaptive operational strategy for enhanced provision of frequency containment reserve by Wind Turbines : data-driven based power reserve adjustment Universiteit Gent
Due to the growing penetration of renewables, Wind Turbines (WT) are becoming increasingly crucial for grid balancing services, such as Frequency Containment Reserve (FCR). This study proposes an adaptive operational strategy that optimally accommodates the power reserve and controls the active power based on grid frequency uncertainties and stochastic wind variations. The proposed approach includes an end-to-end solution, considering fixed and ...
An optimal operation strategy for collaborative flexibility provision of a carbon capture and utilization process with wind energy Universiteit Gent
Improving power system flexibility by responsive demand is essential for integrating wind energy with a high level of variability in power systems. Carbon dioxide-based chemical processes as energy-intensive industrial loads may offer a vast potential of new forms of flexible operation due to their existing control infrastructure and storage capabilities. However, a collaborative decision model is needed for optimal energy sharing among the ...

Wing deformation of an airborne wind energy system in crosswind flight using high-fidelity fluid–structure interaction Universiteit Gent
Unsteady aerodynamic simulations of an airborne wind energy reference system in realistic flight conditions using computational fluid dynamics Universiteit Gent
Comparative study of sample based model predictive control with application to autonomous racing Universiteit Gent
In this paper we outline some of the numerical heuristics used in existing sample-based MPC techniques and present a generic sample-based MPC algorithm for nonlinear optimal control. Compared to most of the existing techniques our generic algorithm does not place any restrictions on the form of the cost functions and dynamics used in the control problem formulation. We apply the numerical heuristics to the presented algorithm and compare their ...
