Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

This paper describes the control theory behind a new group of wind energy systems known as Airborne Wind Energy Systems (AWES). The control architecture of a kite system and rigid body system is explored and this is then compared to a lighter than air system developed by Altaeros Energies. The plant model of this system is described in detail and the main dynamics of the system are outlined. This paper concludes with a simulation study looking at pitch and altitude control using a multivariable PID control strategy. This was developed using the Pettinen-Koivo method and tuned on a linearized model of the Altaeros System. Results show good tracking in both altitude and pitch set-points.
