Previous application of graphene oxide (GO) in recycled aggregate concrete (RAC) is the direct replacement cement or binder to achieve performance improvement. To develop a more efficient (RA) modification technique and improve properties corresponding RAC, this paper performed GO solution pre-spraying pre-soaking treatment on RA. The efficiency was evaluated by compressive strength, interfacial transition zone (ITZ) properties, chloride ion permeability RAC. results show that methods...
In contrast with most existing results concerning unmanned aerial vehicles (UAVs) wherein two-degree or only attitude/longitudinal dynamics are considered, this article proposes an event-triggered cooperative synchronization fault-tolerant control (FTC) methodology for multiple fixed-wing UAVs whose six-degree-of-freedom (DOF) twelf-state-variables subject to actuator faults, modeling uncertainties, and external disturbances. More precisely, event-triggering mechanism is devised determine...
Compared with most existing results concerning unmanned aerial vehicles (UAVs) wherein two-degree or only attitude/longitudinal dynamics are considered, this paper proposes an event-based fault-tolerant coordinated control (FTC) for multiple fixed-wing UAVs such that the consensus tracking of velocity and attitude is achieved in presence actuator faults, external disturbances modeling uncertainties. More precisely, as opposed to static event-triggered communication mechanisms, a dynamic...
Summary This article studies the adaptive model predictive control with extended state observers (ESO) to deal multiple unmanned aerial vehicles formation flight in presence of external disturbances and system uncertainties. Specifically, mismatch caused by uncertainties, ESOs are introduced estimate lumped disturbances, where ultimately bounded property observer can be guaranteed using Lyapunov stability theorem. With these observations, distributed controller is designed achieve trajectory...
Abstract This paper is devoted to the cooperative tracking control of multiple unmanned aerial vehicles with unknown faults. Considering practical case that suffer from strong nonlinearities, external disturbances, actuator, and sensor faults, this brief investigates distributed adaptive fault tolerant scheme for multi‐unmanned vehicle system within model predictive framework. Firstly, preparation occurrence case, baseline designed under fault‐free case. Then considering occurrence, a...
In contrast with most existing results concerning unmanned aerial vehicles (UAVs) wherein material points or only attitude/longitudinal dynamics are considered, this article proposes a distributed fixed-time fault-tolerant control methodology for networked fixed-wing UAVs whose six-degree-of-freedom twelf-state-variables subject to actuator faults and full-state constraints. More precisely, state transformations the scaling function devised keep involved velocity attitude within their...
This research used waste ceramic powder (CP) to replace aggregate, fly ash (FA) as filler, and combined them with sulfur prepare composite cementitious materials. The variations of the mechanical properties aggregate proportions (aggregate mass/total mass) 65%, 70%, 75%, FA contents (FA mass/aggregate filler 0%, 10%, 20%, 30%, 40%, 50% were studied. correlation evaluation model content, CP was established using gray theory, comprehensive property foundation entropy method. Finally, optimum...
