Modelling, analysis and synthesis of some structures for networked control

Abstract

The Ph.D. Thesis addresses the main inherent issues in networked control systems. First, a unified and systematic framework is outlined, which captures all network transmission phenomena from an input-output perspective along with possible data handling strategies as an aid for different control solutions. Then, a mathematical model, which captures simultaneously all the identified network transmission phenomena, is developed for the analysis and synthesis of future network control structures. Finally, the thesis focuses on the design of two types of control strategies for compensating the network induced disturbances – one based on disturbance observers and the other one based on switched compensators – along with the stability analysis and performance evaluation.
