On the Problem of Delay and Packet Dropout in Networked Adaptive Systems

Switching to improve performance in a class of networked decentralized adaptive systems

“…Each model M ij,l has an associated controller C ij,l . The output of the controller is determined according to (13). These N j models are initialized arbitrarily in the parameter space.…”

“…Further, it is apparent that very little work has been carried out when the underlying system is unknown. The first attempt was perhaps in [13] to address simultaneously the problems of packet delay and packet dropout, and, at the same time, achieve asymptotic tracking of an a priori specified desired trajectory when the parameters of the controlled system are unknown. The transient performance was further improved in [14] using the methodology of multiple models, switching, and tuning, and the concept extended to distributed systems in [15] and to a class of networked nonlinear systems with unknown parameters in [11].…”
