This talk introduces a general framework for analyzing the stability of a class of nonlinear networked control systems (NCS) with disturbances in the setting of Lp stability. We provide sharper results for both Lp gain and maximum allowable transfer interval (MATI) and detail the property of uniformly persistently exciting scheduling protocols. This class of protocols were shown to lead to Lp stability for high enough transmission rates and were a natural property to demand, especially in the design of wireless scheduling protocols. Our results apply to a wide range of network protocols, including those built on collision-sense multiple access (CSMA) style protocols, with Ethernet and 802.11a/b/g as prime examples of this class where we also model and derive results for stochastic systems with packet dropouts.
The speaker is currently completing his PhD thesis in the area of networked control systems and is a Victoria Fellow. He has a BSc in pure mathematics and BE with honours in electrical engineering.
