An H2 servo controller is proposed for networked control systems. The network-induced delay is assumed to be time-varying and vary in the known range. The proposed controller guarantees stability and H2 performance for all timevarying delay in the known range. The proposed controller is verified using a simple networked motor control system.

Supposing that the sensor and controller nodes were time-driven and the actuator node was event-driven, the problem of integrity against sensor failures for the networked control systems with short output delay and short control delay was discussed based on observer. The state observer of the system according to the time-delay compensation strategy was designed. Then, considering possible senso...

In this paper we present a general framework for networked control systems, where all components are assumed to be connected through a communication network. We use the uncertainty threshold principle to show that under certain conditions there is a rate for dropped packets for which an undisturbed networked control system is mean square stable.

Title of dissertation: CONTROL OF NETWORKED ROBOTIC SYSTEMS Yen-Chen Liu, Doctor of Philosophy, 2012 Dissertation directed by: Professor Nikhil Chopra Department of Mechanical Engineering and Institute for Systems Research With the infrastructure of ubiquitous networks around the world, the study of robotic systems over communication networks has attracted widespread attention. This area is den...

This chapter investigates the cooperative control problem for a group of Lagrange systems with a target system to be tracked. The development is suitable for the case that the desired trajectory of the target node is only available to a portion of the networked systems. All the networked systems can have different dynamics. The dynamics of the networked systems, as well as the target system, ar...

This chapter discusses networked robots, multiple robots operating together coordinating and cooperating by networked communication to accomplish a specified task. This chapter presents an overview of the field with an emphasis on recent results and research challenges. Multiple robots enable new capabilities and the communication network enables new approaches and solutions that are difficult ...

Abstract: In the networked control system (NCS), the uncertain network-induced delay and nonlinear controlled object are the main problems, because they can degrade the performance of the control system and even destabilize it. In this paper, a class of uncertain and nonlinear networked control systems is discussed and its sufficient condition for the robust asymptotic stability is presented. F...

This paper discusses a novel approach to specificationbased intrusion detection in the field of networked control systems. Our approach reduces the substantial human effort required to deploy a specification-based intrusion detection system by automating the development of its specification rules. We observe that networked control systems often include comprehensive documentation used by operat...
