The mathematical transforms used in Phase-Locked Loops (PLLs) play a crucial role in their performance and functioning. Depending on the format of the control loop's input signal, noise level requirements and other requirements such as available computational power, one must choose which topology best suits a given application. This article will address the most used transforms and filters in the most common PLL topologies, such as the Clarke Transform, the Park Transform, the Second-Order Generalized Integrator (SOGI) filter and the Hilbert Transform. Finally, a comparison of the advantages and disadvantages of each of these methods is discussed.
Soft robots have been receiving unprecedented attention in recent years for being able to be used side-by-side with humans, exploring dangerous environments and confined spaces, moving across uneven terrain, and solving problems that rigid robots cannot solve. The wide range of additive manufacturing techniques has also boosted research in the area. This work summarizes the characteristics of the five most relevant techniques – FDM, DIW, SLS, Inkjet, and SLA – for fabricating soft robots together with case studies. A summary contains models of industrial-sized additive manufacturing machines that can compose a facility for fabricating large-scale soft robots.
This article proposes an approach based on Industry 4.0 technologies for building smart-warehouses aiming to improve the performance of this logistic system operation. A general and scalable logical warehouse architecture was developed to increase the traceability, reliability, and agility of intralogistics activities. When modeling and simulating the proposal presented to build a testbed, potential gains were observed such as structuring and well-organized operations, orchestration of technological resources to improve logistical performance, reduction of human intervention in the process, increased productivity, and proof of operation errors.
This article proposes an approach based on Industry 4.0 technologies for building smart warehouses aiming to improve the performance of this logistic system operation. It is considered that the development of general and scalable logical warehouse architecture was to increase the traceability, reliability, and agility of intralogistics activities. It was observed potential gains (structuring and well-organized operations, orchestration of technological resources to improve logistical performance, reduction of human intervention in the process, increased productivity, and proof of operation errors) when modeling and simulating the proposal presented to build a testbed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
