High-Performance Industrial Wireless: Achieving Reliable and Deterministic Connectivity over IEEE 802.11 WLANs

<div>Communication for control-centric industrial applications is characterized by the requirements of very high reliability, very low and deterministic latency and high scalability. This paper proposes a novel solution for providing reliable and deterministic communication, through Wi-Fi, in industrial environments. The proposed solution, termed as HAR²D-Fi, adopts hybrid channel access mechanisms for achieving deterministic communication. It also provides temporal redundancy for enhanced reliability. HAR²D-Fi implements different medium access control (MAC) designs that build on the standard physical (PHY) layer. Such designs can be classified into two categories: (a) MAC designs with pre-defined (physical) time-slotted schedule, and (b) MAC designs with virtual time-slotted schedule. Performance evaluation, based on analysis and system-level simulations, demonstrates the viability of HAR²D-Fi for control-centric industrial applications.</div>

Geometrical Model of Fixed Parts and Movable Parts Projected Shaft Star of SIRM by GA and Conventional Method to Minimize the Pulling Force Fluctuation

In this article, focus on modeling of switched reluctance motor (SiRM) The flux assets of the iron, the number of phases, and the number of projected portion per phase all have a irregular properties on this Devices. These possessions, along with the sizing of the Device cover and internal scopes, kind the Device project an insight-intensive struggle. Enlargement of pulling force density, power output, and lowering location of pulling force fluctuation, heat escalation, audio sound. A design organization that exploits the desired features and reduces the undesirable effects is obtainable here. Static and dynamic system-level simulations and finite-element analysis have been accepted out for a 3-phase 6/4 2.4-kW SIRM, at various rated electrons flow assessment for both conventional design and genetic procedure design methods and the results were verified using standard reproductions. The result seems to be stirring. The results demonstrate suitable projected shaft star Curve and movable parts Curve of a pulling force –fluctuation minimized SiRM drive.
