Open Access research which pushes advances in bionanotechnology

Strathprints makes available scholarly Open Access content by researchers in the Strathclyde Institute of Pharmacy & Biomedical Sciences (SIPBS) , based within the Faculty of Science.

SIPBS is a major research centre in Scotland focusing on 'new medicines', 'better medicines' and 'better use of medicines'. This includes the exploration of nanoparticles and nanomedicines within the wider research agenda of bionanotechnology, in which the tools of nanotechnology are applied to solve biological problems. At SIPBS multidisciplinary approaches are also pursued to improve bioscience understanding of novel therapeutic targets with the aim of developing therapeutic interventions and the investigation, development and manufacture of drug substances and products.

Abstract

As wind turbines increase in size, the tasks being assigned to the controller increase and their design becomes more demanding; in particular, the controller may be required to reduce the tower fatigue loads. The basic approach to tower load fatigue reduction is to employ a tower feedback loop (TFL). It typically achieves a 4%-7% fatigue load reduction depending on the details of the wind turbine. In this paper, the concept of a co-ordinated (CCD) controller is analysed which aims to increase the tower fore-aft load reduction whilst simultaneously reducing the pitch activity.
