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

    The main aim of the present project is to obtain a better understanding of the dynamic control of a wind turbine. To accomplish this, an adaptive dynamic controller was developed and connected to a wind DFIG Simulink model. In order to demonstrate the effectiveness of the controller in question, a three phase fault in the power grid was simulated. Results showed how the implementation of the adaptive dynamic programming controller helped to improve the speed of response of the system. It also helped to reduce the magnitude of the oscillations taking place after the disturbance is removed. The non-linear systems are difficult to model and to control. New modern control techniques allow controlling these systems without having the system model, reducing the complexity. Among these techniques, it is the adaptive dynamic control that estimates the parameters of the dynamic system on-line and adapts their control to the new conditions without spreading the error throughout a feedback network.
