Data-Driven LIDAR Feedforward Predictive Wind Turbine Control

Light Detection and Ranging (LIDAR)-assisted Model Predictive Control (MPC) for wind turbine control has received much attention for its ability to incorporate future wind speed disturbance information in a receding horizon optimal control problem. However, the growth of wind turbine sizes results in increasing system complexity and system...

Data-enabled predictive control with instrumental variables: the direct equivalence with subspace predictive control

Direct data-driven control has attracted substantial interest since it enables optimization-based control without the need for a parametric model. This paper presents a new Instrumental Variable (IV) approach to Data-enabled Predictive Control (DeePC) that results in favorable noise mitigation properties, and demonstrates the direct equivalence...

Towards Convex Economic Model Predictive Individual Pitch Control for Wind Turbine Load Mitigation

Wind turbines offer an appealing method for power generation. In the fight against global warming wind energy helps realise green house gas emission reduction targets. Moreover, given a globally increasing demand for energy, the role of wind energy is set to become even more important. Historically, the cost of wind energy has decreased...

A probably minor role for land-applied goat manure in the transmission of Coxiella burnetii to humans in the 2007–2010 Dutch Q fever outbreak

In 2007, Q fever started to become a major public health problem in the Netherlands, with small ruminants as most probable source. In order to reduce environmental contamination, control measures for manure were implemented because of the assumption that manure was highly contaminated with Coxiella burnetii. The aims of this study were 1) to...

Lifetime City & Theater City

The ambition of the Yongsan theatre is to bring people together. It is a truly public domain that is open to everyone. The new theater in the heart of Yongsan attracts people from around the neighbourhood, but also people from outside Yongsan, that come by the adjacent station, or by car. The building attracts visitors from all ages. Both young...

GMRES(m) with de ation applied to nonsymmetric systems arising from fluid mechanics problems

The computational simulation of many engineering problems requires solving linear, sparse, systems of unknowns. Also in the field of aerodynamics, where discretization of equations governing ow problems produces these systems. Improving efficiency of iterative methods used for solving these systems decreases the costs of simulations and is...
