Autonomous underwater vehicles (AUVs) are submersible controlled by onboard computers. AUV formation is a cooperative control which focuses on controlling multiple AUVs to move in group while executing tasks. In contrast single AUV, multi-AUV represents higher efficiency and better stability for many applications, such as oil gas industries, hydrographic surveys, military missions, etc. To achieve formation, there several key factors, including performance, control, communication capability....

In this article, the adaptive control for a class of strict-feedback nonlinear systems with uncertainties under injection and deception attacks is considered. An scheme proposed to deal meanwhile guarantee that regulation errors could be made arbitrarily small by adjusting parameters. Compared existing works whose models are linear or relatively simple, model we consider in article parametric uncertainties. A new type feedback introduced solve problem. simulation example given verify...

Multiagent systems (MASs) are distributed with two or more intelligent agents. Formation control is a significant technique of MASs. To date, formation on MASs widely used in various fields, such as robots, spacecrafts, satellites, and unmanned aerial/surface/underwater vehicles. However, there relatively small body literature that concerned security problems past years. Our research represents the first step toward developing attacks study aims to investigate potential multirobot system for...

Many applications in scientific and engineering domains are structured as large numbers of independent tasks with low granularity. These thus amenable to straightforward parallelization, typically master-worker fashion, provided that efficient scheduling strategies available. Such have been called divisible-loads because a scheduler may divide the computation among worker processes arbitrarily, both terms number task sizes. Divisible load has an active area research for last 15 years. A vast...

In this article, an optimal control scheme against false data injection (FDI) attacks for multiagent systems with unavailable system states is presented. The output that remains uncorrupted extracted from a group of measurements during FDI using secure preselector. Then, on the basis unattacked data, state observer utilized to identify states. By taking communication overhead into account, event-triggered mechanism employed alleviate burdens. solution problem related Hamilton–Jacobi–Bellman...

In this article, the power distribution and tracking problems of distributed energy storage system (ESS) are addressed by designing a cooperative adaptive terminal sliding mode (CATSM) controller based on multi-agent network topology for each ESS. First, novel allocation algorithm (APAA) is proposed to achieve consistent state-of-charge (SOC) battery in Then, considering capacity degradation during long-term charging discharging, we use real-time current SOC estimate battery, which ensures...

Divisible load applications consist of an amount data and associated computation that can be divided arbitrarily into any number independent pieces. This model is a good approximation many real-world scientific applications, lends itself to natural master-worker implementation, has thus received lot attention. The issue divisible scheduling been studied extensively. However, only few authors have explored the simultaneous multiple such on distributed computing platform. We focus this...

In this article, the event-triggered adaptive output feedback control of multivariable system under nonsmooth actuator nonlinearities, including deadzone, backlash, and hysteresis is investigated. The nonlinearities are handled with a unified framework by modeling them time-varying disturbance input. With an mechanism one-parameter estimation approach, communication consumption for significantly reduced. It shown that all signals in closed loop bounded. Zeno behavior also avoided. simulation...

Recursive Diagonal Torus (RDT), a class of interconnection network is proposed for massively parallel computers with up to 2/sup 16/ nodes. By adding remote links the diagonal directions torus recursively, RDT can realize smaller diameter (e.g., it 11 nodes) number per node (i.e., 8 node) than that hypercube. A simple routing algorithm called vector routing, which near-optima and easy implement also proposed. The comprises mesh structure, emulates hypercube tree structures easily. FFT...

<title>Abstract</title> This study addresses the stability and stabilization challenges in nonlinear control systems with time-varying delays via fuzzy model theory. An exponentially narrow delay interval technique is introduced, facilitated by a single tunable parameter $p$, to equivalently transform extensive period $[d_0, d_2]$ into series of variable subintervals, expressed as: $[d_{0},d_{2}]=\cup_{i=1}^{2^l}[d_{\frac{i-1}{2^{l-1}}},d_{\frac{i}{2^{l-1}}}]$. Diverging from traditional...

In Networks-on-Chip (NoC) designs, crosstalk noise has become a serious issue which may cause the communication channel unreliable. The problem can be mitigated by wide spacing of serial lines. However, wider lines will reduce number lines, thus data throughput. this paper, new fully adaptive multi-path routing (MPR) scheme is proposed to maximize throughput utilizing multiple paths for concurrent transmission. For MPR algorithm, two transport models are considered: full-wire-bank model (FM)...

The routing algorithm of the DTN, which experience frequent long-duration partitions, is quite different from normal networks. Active algorithms usually adopt an active host (data mule/message ferry) to exchange and forward messages. In existing studies in problem generally solved by adopting solutions Travelling Salesman Problem (TSP). such solutions, often finding a simple cycle with no repeated nodes nor edges. By considering more general scenario, we propose algorithm, based on...
