Output feedback networked control with persistent disturbance attenuation

• Present a method for stabilization and rejection of persistent disturbances.
• Consider output feedback using the state observer to estimate states and disturbances.
• Apply in NCS to reduce the number of transmitted messages.
• Improved performance is shown with respect to recent and similar work.

This paper presents a model-based control approach for output feedback stabilization and disturbance attenuation of continuous time systems that transmit measurements over a limited bandwidth communication network. Necessary and sufficient conditions for asymptotic stability of the networked system in the presence of persistent external disturbances are given. The results in this paper provide a significant improvement in the performance of the system and provide a considerably reduction of the necessary network bandwidth with respect to similar approaches in the literature.
