Open Access research with a European policy impact...

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 European Policies Research Centre (EPRC).

EPRC is a leading institute in Europe for comparative research on public policy, with a particular focus on regional development policies. Spanning 30 European countries, EPRC research programmes have a strong emphasis on applied research and knowledge exchange, including the provision of policy advice to EU institutions and national and sub-national government authorities throughout Europe.

Abstract

A simple method for modifying and improving the robustness of LQG optimal controllers is considered. A sensitivity costing term is introduced into the cost index and a fictitious disturbance signal, which affects robustness margins, is discussed. The influence is somewhat different on full-order and restricted-structure designs, and this is explored. Finally, the effect of a coloured measurement noise model on the robustness of the solution is investigated.
