This letter considers the design of a fault-tolerant formation control law for multi-agent systems using energy balancing methods. Decentralized algorithms fault diagnosis and graph topology update are proposed, reconfiguration procedure is developed based on tanks, which able to guarantee that new connections among agents can be established in passive way. A simulation study supports corrobora...

• Direct heat flux sensing for window shade control is investigated the first time. Unprocessed measurements fluctuate too extensively use. Endpoint moving average and infinite impulse response filters provide cleaner signals. Requirements signal persistence over time improve shading accuracy. The resulting system allows to reduce gain extensively. Greenhouse gas emissions from space cooling ar...

Notions of passivity for a class of switched control systems (SCS) are developed first in this article. We then study the following problems: 1) When is an SCS passive? 2) Does passivity imply Lyapunov stability as in the classical passive systems? 3) How to use passivity as a tool to design controllers to stabilize an SCS? For Problem 1), we derive sufficient conditions for passivity. For prob...

Hydraulic systems, as power sources and transmissions, offer many advantages over electromechanical or purely mechanical counterparts in terms of power density, flexibility, and portability. Many hydraulic systems require touching and contacting the physical environments; and many of these systems are directly controlled by humans. If hydraulic systems are passive, they would be both safer to i...

This work presents an overview of some recent developments made by the authors in the field of vibrational control of largescale structural systems subject to seismic excitations. The structural systems under consideration are classified in two broad categories: (i) high-rise buildings, and (ii) multi-building systems. When dealing with high-rise buildings, the inclusion principle can be used a...

This paper concerns the problem of output strictly passive control for uncertain singular neutral systems. It introduces a new effective criterion to study the passivity of singular neutral systems. Compared with the previous approach, this criterion has no equality constraints. And the state feedback controller is designed so that the uncertain singular neutral systems are output strictly pass...

This paper provides a sufficient framework to synthesize l-stable networks in which the controller and plant can be subject to delays and data dropouts. This framework can be applied to control systems which use “soft-real-time” cooperative schedulers as well as those which use wired and wireless network feedback. The framework applies to plants and controllers which are passive, therefore thes...
