In this paper we introduce a novel control network protocol , Try-Once-Discard (TOD), for networked control systems (NCS), and provide, for the rst time, an analytic proof of global exponential stability for both the new protocol and the commonly used statically scheduled access methods. Controllers are designed without regarding the presence of the network(More)
– The deÞning characteristic of a networked control system (NCS) is having a feedback loop that passes through a local area computer network. Our two-step design approach includes using standard control methodologies and choosing the network protocol and bandwidth in order to ensure important closed-loop properties are preserved when a computer network is(More)
The deening characteristic of a networked control system (NCS) is having a feedback loop that passes through a local area computer network. This paper considers nonlinear systems controlled in this manner, and demonstrates that for suuciently high transmission rates, the network may be considered transparent. Three methods of scheduling data packets are(More)
—In many applications of multi-agent systems (MAS), a set of leader agents acts as control inputs to the remaining follower agents. In this paper, we introduce an analytical approach to selecting leader agents in order to minimize the total mean-square error of the follower agent states from their desired value in steady-state in the presence of noisy(More)
In this paper we develop and analyze spiking neural network (SNN) versions of resilient propagation (RProp) and QuickProp, both training methods used to speed up training in artificial neural networks (ANNs) by making certain assumptions about the data and the error surface. Modifications are made to both algorithms to adapt them to SNNs. Results generated(More)
— Commercial aviation is at the threshold of the era of the e-enabled airplane, brought about by the convergence of rapidly expanding worldwide data communication infrastruc-tures, network-centric information processing and commoditized lightweight computational hardware. With advanced avionics, processing and wireless communication capabilities, the(More)
In leader-follower systems, follower nodes receive inputs from a set of leader nodes, exchange information, and update their states according to an iterative algorithm. In such algorithms, the node states may deviate from their desired values before the algorithm converges, leading to disruptions in network performance. In this paper, we study the problem(More)
T he title of this special section updates a common juxta-position in control circles. The scale of applications of interest is no longer captured simply by " systems and control " ; it is increasingly the networked nature of systems that is drawing attention. This special section presents five articles that can be classified into two distinct areas of "(More)
