This article presents scalable controller synthesis methods for heterogeneous and partially systems. First, systems composed of different subsystems that are interconnected over a directed graph considered. Techniques from robust gain-scheduled employed, in particular, the full-block S-procedure, to deal with decentralized system part nominal condition interconnection multiplier condition. Unde...

This paper investigates a distributed formation tracking control law for large-scale networks of mechanical systems. In particular, the network is represented by directed communication graph with leaders and followers, where each agent described as port-Hamiltonian system constant mass matrix. Moreover, we adopt parameter approach to prove scalable asymptotic stability formation, i.e., scalabil...

Distributed hardware systems can be considered as teams of distributed cooperative agents. Thinking this way, will power the designers to develop new agent-based ideas to increase systems’ fault tolerance. In this paper, recovering the system from potential faults by helping the faulty agents in performing their tasks is considered. Besides, each agent, through two phases of distributed decisio...

This paper describes the mechanisms employed to control access to system services on the IFS project. We base our distributed computing environment on systems that we trust, and run those systems in physically secure rooms. From that base, we add services, modifying them to interoperate with existing access control mechanisms. Some weaknesses remain in our environment; we conclude with a descri...
