— This article reports on the development and implementation of an algorithm for the design of spatially-distributed feedback controllers for the wide variety of physical processes that are included in cross-directional control of industrial paper machines. The spatial and temporal structure of this class of process models is exploited in the use of the two-dimensional frequency domain for anal...

This paper addresses the distributed attitude synchronization problem of multiple spacecraft with unknown inertia matrices. Two distributed adaptive controllers are proposed for the cases with and without a virtual leader to which a time-varying reference attitude is assigned. The first controller achieves attitude synchronization for a group of spacecraft with a leaderless communication topolo...

In This research work we discussed about Networked control systems (NCS) for controlling flow rate of two nonintrecting tank processes using ANN controller. Basically NCS are used for distributed computing and control systems with sensors, actuators and controllers that communicate over a shared medium. The distributed nature of NCS and issues related to the shared communication medium pose sig...

The paper presents the design and control strategy of an isolated DC microgrid, which is based on classical techniques, predictive iterative algorithms. parameters are maximum overshoot, settling time voltage ripple. designed to operate in two different modes, end-users minimum demand scenarios, this achieved through incorporation network dynamic loads. methodology developed allows obtain a fas...

This paper proposes a novel distributed secondary controller for droop-controlled microgrids to regulate the frequency and voltage, autonomously share power mismatch. The proposed scheme is entitled generalized proportional-intergal finite-time (GPI-FTC). GPI-FTC synthesized based on control Lyapunov function method modifying conventional PI by adding consensus term integrand dynamic. provides ...

Distributed software-defined networks (SDN), consisting of multiple inter-connected network domains, each managed by one SDN controller, is an emerging networking architecture that offers balanced centralized control and distributed operations. In such paradigm, most existing works focus on designing sophisticated controller-synchronization strategies to improve joint controller-decision-making...

-we present in this work a cooperative control paradigm for the autonomous navigation of a mobile robot and demonstrate that the cooperative controller learns faster and better than a centralized one. Behaviors emerge from the neuro-evolved controller, in order to achieve a designed task and without been defined at design stage. In our proposal, a robotic agent is divided into sub-agents, each ...

This paper presents a performance optimization algorithm for controller reconfiguration in fault tolerant distributed model predictive control for large-scale systems. After the fault has been detected and diagnosed, several controller reconfigurations are proposed as candidate corrective actions for the fault compensation. The solution of a set of constrained optimization problems with differe...

Rigidity of formations in multi-robot systems is important for formation control, localization, and sensor fusion. This work proposes a rigidity maintenance gradient controller for a multi-agent robot team. To develop such a controller, we first provide an alternative characterization of the rigidity matrix and use that to introduce the novel concept of the rigidity eigenvalue. We provide a nec...
