Robust H-Infinity Filtering for Networked Control Systems with Markovian Jumps and Packet Dropouts

This paper deals with the H ∞ filtering problem for uncertain networked control systems.In the study, network-induced delays, limited communication capacity due to signal quantization and packet dropout are all taken into consideration.The finite distributed delays with probability of occurrence in a random way is introduced in the network.The packet dropout is described by a Bernoulli process.The system is modeled as Markovian jumps system with partially known transition probabilities.A full-order filter is designed to estimate the system state.By linear inequality approach, a sufficient condition is derived for the resulting filtering error system to be mean square stable with a prescribed H ∞ performance level.Finally, a numerical example is given to illustrate the effectiveness and efficiency of the proposed design method.
