Mean‐square stability of networked control systems with event driven state quantisation and packet loss

Abstract

This study addresses mean-square stability of networked control system with state quantisation process and suffers random packet losses. A logarithmic quantiser is applied in order to decrease the possibility of the packet loss phenomenon. Also, the quantisation process is designed as event driven so that the quantisation is only performed when necessary. It is shown that stability in mean-square sense is achieved if a series of LMI conditions are valid. Simulations are finally performed to show the effectiveness of the results of the theoretical analysis.
