Abstract:

The characteristics of asynchronous networked control systems with single-packet transmission, multiplepacket transmission, data packet dropout in the presence of short time delays, and single-packet transmission in the presence of long-time delays are analyzed. The asynchronous clock and the state fe  edback are considered in this paper. Based on it, the uniformed modeling method for networked control systems with the above different network condition s is developed first. The building of discrete state-space models including system noise provides a basis for the exact identification and effective con  trol.
