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

When PID controllers receive the sensor information or transmit its outputs through a communication network, its parameters are difficult to tune using classical PID tuning methods. This is due to stochastic delays introduced by the network in the feedback loop. This paper proposes a design method to compensate the effects of this delay using a constrained optimization to find the PID parameters. The design is based on a polytopic description of the system, which can be formulated using a pdf distribution of the delay. Simulation results are presented to demonstrate the performance of the proposed method.
