Resource scheduling problems (RSPs) in cloud manufacturing (CMfg) often manifest as dynamic which strategies depend on real-time environments and demands. Generally, multiple resources the CMfg process cause difficulties system modeling. To solve this problem, we propose Sharer, a deep reinforcement learning (DRL)-based method that converts with into one target learns effective automatically. Our preliminary results show Sharer is comparable to latest heuristics, adapts different conditions,...

Abstract The perching behavior of birds is very common in nature, but it extraordinary for fixed‐wing unmanned aerial vehicles (UAVs), because post‐stall maneuver. main problems the maneuver are weak control authority and strong model nonlinearity. This paper proposed a method to realize perch For problem authority, an optimal trajectory designed. And feasible reference given under conditions dynamic characteristics actuator constraints. nonlinearity, singularity‐free online neural...

Integrating Multi-access Edge Computing (MEC) in Low Earth Orbit (LEO) network enables all user equipment on the ground to receive MEC services with low service latency relatively. Service request scheduling can realize effective utilization of various resources and system, guarantee performance system. deployment are closely related. Therefore, joint problem (SDRS) is modeled as an optimization problem, which a mixed integer linear programming problem. Our goal reduce proportion...

View Video Presentation: https://doi.org/10.2514/6.2021-3005.vid This paper presents a novel Extended Incremental Nonlinear Dynamic Inversion (EINDI) approach, which brings the maximum rate ability of actuators into full play that conventional INDI approach could not achieve in case where pure time delay/post filter exists flight control system. The output is actually actuator command. Based on this principle, we propose two EINDI methods, with first one disconnecting both feedbacks surface...

The increased amount of redundant units means improvement task reliability, however, the additional and corresponding vote devices request more logistics, which results in decline basic reliability. In this paper, we design make analysis comparison multiple structures two ways reliability This paper provides theoretical reference for FCS redundancy design.

This thesis has designed a remote control system which takes Micro controller Unit AT89S51 as the core for library temperature and humidity.The consists of humidity data acquisition, wireless transceiver, PC display modules. The can detect remotely in real time, avoid traditional manual labor tedious, contribute to storage paper documents.

To ensure the reliability of wafer stage system lithography, all factors affecting were analyzed. A new method based on experts grading method[1] and analytic hierarchy process(AHP)[2] is developed to allocate indices system. This approach considers not only experience knowledge expert, but also combines Comparative Matrix process reduce defect that stronger subjective method. Finally, a certain lithography was taken as an example, allocation obtained. The result indicate proposed feasible effective.

A mathematic model of capstan drive stiffness is presented. The influence preload force, coefficient friction, wraps cable and load on the transmission a differential cable-driven picking manipulator analyzed. It shown that capability transmission, loads precision can be considered comprehensively in design capstan.

Cloud manufacturing is a new type of modern mode. The Manufacturing Service Composition (CMSC) one the key issues cloud manufacturing. quality and efficiency services are influenced by rationality optimisation model. Previous studies have rarely considered impact cooperation between on service composition. In this paper, Cooperation Level (SCL) evaluation mechanism corresponding update model proposed to dynamically measure level services. Furthermore, novel with Evaluation (CMSC-SCLE)...

Engineering experience reminds us of the importance uncertainty analysis in fatigue reliability based design. In present paper, according to procedure analysis, parameter and model are studied corresponding solutions reviewed. The aim is obtain index quantify uncertainties imported by parameters. current research focuses on defining putting forward different methods handle variable expressions (random, convex, fuzzy set). Different from can reduce modifying structure or selecting best model....

The consists of Unit, SHT75 sensor, Rok 101 007 wireless transceiver and PC data display modules. can detect in room Bikram's yuga remotely to create an environment suitable for fitness high temperature.

Fruit picking is a seasonal and labor-intensive work. The industry requires automatic fruit due to increasing labor costs variability in skill. High accuracy, simple structure low cost are expected make the robot be readily accepted widely used. Cable-driven transmission more preferable than traditional system for some of its merits benefiting production small light-weight manipulator. In this paper, design differential cable-driven manipulator presented. Different way analyzed compared....
