Output Feedback Model-Based Control of uncertain discrete-time systems with network induced delays

A new architecture for model-based control of unstable and uncertain systems with network induced delays, and for set-point tracking over networks, is presented in this paper. This setup provides better performance than similar approaches in terms of steady-state tracking error and reduction of network traffic by transmitting measurement updates only when necessary. The results in this paper also extend previous work using the Model-Based Networked Control Systems (MB-NCS) approach to consider the output feedback case and to consider models and uncertain systems which do not necessarily have the same dimension; that is, both the parameters and the order of the system are unknown. The Model-Based Event-Triggered (MB-ET) framework presented in this paper is used for stabilization and tracking of piece-wise constant signals and it is extended in two directions; first, to consider a more general two channel networked system and second, to address the reference input tracking problem in the presence of network induced delays.
