This paper investigates the leader-follower formation problem for a group of quadrotors. Finite-time control scheme and prescribed performance method, which are regarded as two highlights, introduced in this paper. First, with is used to translational movements ensure quadrotors obtain relative gentle transient process an adjustable steady-state error bound. Then, desired orientations rotation subsystem provided by part stabilised fixed-time law. Finally, designing finite-time controller,...
In this article, the problem of tracking control is considered for a class uncertain strict-feedback nonlinear systems with deferred asymmetric time-varying full-state constraints. A novel adaptive robust full-state-constrained scheme developed. First, by introducing shifting function, original constrained system any initial values modified to new system, and remain 0. Then, remove feasibility condition caused barrier Lyapunov functions, further transformed into unconstrained brand...
Enhancing spray cooling with surface structures is a common, effective approach for high heat flux thermal management to guarantee the reliability of many high-power, high-speed electronics and improve efficiency new energy systems. However, fundamental transfer enhancement mechanisms are not well understood especially nanostructures. Here, we fabricated six groups nanowire arrayed surfaces various sizes that show first time how these nanostructures enhance by improving wettability liquid...
This paper presents a novel control scheme for the trajectory tracking in quadrotor. First, kinematics and dynamics models of quadrotor with uncertainties are developed by Newton–Euler method. For nonlinear coupling dynamic, unmodeled external disturbances, an effective linear extended state observer is designed to estimate them. Then, overall system divided into two subsystems: translational subsystem rotational subsystem. subsystem, attitude controller dual-loop integral sliding mode...
Surface-enhanced Raman spectroscopy (SERS) is an emerging technique for the detection of pesticide residues on food surfaces, permitting quantitative measurement without pretreating sample. However, previous studies have mainly involved single spectrum samples, while given little information residue distribution. In this paper, gold nanoparticles were used as surface enhancers to obtain spectra omethoate and chlorpyrifos, using shifts 413 cm-1 (omethoate) 346 & 634 (chlorpyrifos) peaks...
ABSTRACT The SARS-CoV-2 pandemic and the emergence of novel variants underscore need to understand host-virus interactions identify host factors that restrict viral infection. Here, we perform a genome-wide CRISPR knockout screen restriction for SARS-CoV-2, revealing DAZAP2 as potent antiviral gene. DAZAP2, previously implicated in restriction, is found inhibit entry by blocking virion fusion with both endolysosomal plasma membranes. Additionally, suppresses genomic RNA replication without...
Recycled concrete aggregate (RCA) has excellent mechanical properties and is often used as base course in pavement construction. However, highly alkaline leachate from RCA been observed laboratory studies. The associated high-pH leaching patterns can be of concern, especially when compared to the neutral pH environment actual road sections using course. In this study, pH-dependent concentrations trace elements copper (Cu) zinc (Zn) oxyanion chromium (Cr) were investigated on unfractionated...
In this article, we study the tracking problem for networked nonlinear discrete systems with actuator faults and dual-direction data dropouts. A novel adaptive fault-tolerant iterative learning model-free control strategy is designed. First, by utilizing method called compact form dynamic linearization, original system model transformed into an equivalent data-driven model, contains only one unknown parameter. Both fault dynamics information are included in Then, to physical processes of...
This paper proposes a novel control strategy to solve the tracking problem for uncertain vehicle active suspension systems (VASS). Under proposed framework, overall VASS is divided into two subsystems owing its particular structure: (1) first subsystem, ensure important state variable within given restrictive conditions all time, prescribed performance control(PPC)-based intermediate controller designed; furthermore, new relative threshold event-triggered based on theory; Moreover, because...
This article addresses the distributed consensus tracking problem for high-order nonlinear multiagent systems (MASs) with nonidentical output constraints under directed switching graphs. Such a practical and important issue has only been taken into limited consideration by existing literature. In this article, heterogeneous followers are considered to suffer from constraints, which take precedence over tracking. To end, series of intermediate dynamic variables introduced each agent isolate...
This study considers the tracking control problem of an uncertain quadrotor unmanned aerial vehicle with model uncertainties and wind gust disturbances, a novel robust dynamic surface based multiple state variables constrained scheme is proposed. Under presented framework, overall system decoupled into translational subsystem rotational subsystem. These two subsystems are connected to each other through common attitude extraction algorithms. For subsystem, inputs designed ensure within...

In this article, the iterative learning averaging consensus problem is studied for multiagent systems with system uncertainties, actuator faults, and binary-valued communications. Considering only measurement information stochastic noise can be received from its neighbors each agent, a new two-iteration-scale framework that alternates estimation control designed. Under proposed framework, agent estimates neighbors' states based on empirical method during dwell iteration interval, which...
