Joint Representation

This article deals with the problem of joint representation of mechanical and motion control information of machines with servo axes. A new conceptual model is proposed for the graphical representation of industrial mechatronic systems covering the minimum information requirements from both mechanical and motion automation points of view. The model also takes into account new electronic motion control concepts such as virtual axes and temporary electronic coordination relationships between axes (e-gears). The objective is to support more integrated and collaborative work between mechanical designers and automation developers when implementing complex machines and industrial mechatronic systems. Schemes graphically representing the relevant common information are obtained from the information model, which may simplify the exchange of information between the mechanical and the motion control fields, not only at conceptualization and design stages, but also throughout the rest of the implementation process of industrial mechatronic systems.

The Relationship

The socio-legal perspective on the alcohol legislation, including the norms concerned with the relationship between individuals and alcoholic drinks, helps answering some essentials questions: what was/is the "social construction" of the alcohol problem in different eras and different cultures and, consequently, which objectives are deemed to be worthy of pursuit through the creation or amendment of legislation? Which social actors have the ability, in a given period of time, to inscribe the relevance of innovative alcohol legislation on the political agenda and what kind of dialectic is used among those who champion points of view, competences and above all, different interests? Which interests and values would appear to meet with legislatory protection time after time? What tools, of the ample range available, are chosen to achieve the aims set out? To what extent is legislation implemented (or not implemented), and why? Which aspects of the implementation process prove to be most significant, i.e. define the actual content of the legislation "in force", and are therefore tangibly experienced by the law's end target? How much of an impact does legislation have on behavior which is subject to regulation or on problems which stem from such behavior?

In view of the future lack of human resources due to the aging of the population, the automatic, Intelligent Mechatronic Systems (IMSs) and Intelligent Transportation Systems (ITSs) have broad application prospects. However, complex application scenarios and limited open design resources make designing highly efficient ITS systems still a challenging task. In this paper, the optimal load factor solving solution is established. By converting the three user requirements including working distance, time and load into load-related factors, the optimal result can be obtained among system complexity, efficiency and system energy consumption. A specialized visual navigation and motion control system has been proposed to simplify the path planning, navigation and motion control processes and to be accurately calculated in advance, thereby further improving the efficiency of the ITS system. The validity of the efficiency calculation formula and navigation control method proposed in this paper is verified. Under optimal conditions, the actual working mileage is expected to be 99.7%, and the energy consumption is 83.5% of the expected value, which provides sufficient redundancy for the system. In addition, the individual ITS reaches the rated operating efficiency of 95.86%; in other words, one ITS has twice the ability of a single worker. This proves the accuracy and efficiency of the designed ITS system.

Points Of View

The aim of this manuscript is to define an operational pipeline of work, from data acquisition to the report creation, for the smart management of PV plants. To achieve such an ambitious result, we exploit the implementation of a conceptual model, deployed through a relational database to retrieve any kind of information related to the PV plant. The motivation that drove this research is due to the increasing construction of PV plants. In fact, following European and international investments that heavily stimulated the use of clean energy, the need to maintain PV plants in their maximum efficiency for their whole lifecycle emerged, to bring about benefits from both the ecological and the economic points of view. While the research community focuses on finding new and automatic ways to detect faults automatically, few efforts have been made considering the so-called Operation and Maintenance (O&M). A relational conceptual model may facilitate the management of heterogeneous sources of information, which are common in complex PV plants. The purpose of the present study is to provide companies and insiders with a GIS-based tool to maintain the energy efficiency of a PV plant. Indeed, it is a common practice used by companies dealing with O&M of PV plants to create technical reports about the health status of the plants. This operation, made manually, is very time consuming and error prone. To overcome this latter drawback, this work attempts to encourage the use of GIS in the PV plants O&M, which proves to be efficient to deal with fault management and to assure a good level of energy production. The developed conceptual model, tested on two real case studies, proved to be complete, cost-effective and efficient to be replicated in other existing plants.

Abstract The paper concerns development of original method of optimal control at energy performance index and its application to dynamic processes surveillance of some mechatronic systems. The latter concerns chatter vibration surveillance during highspeed slender milling of rigid details, as well as motion control of two-wheeled mobile platform. Results of on-line computer simulations and real performance on the target objects reflect a great efficiency of the processes surveillance
