Abstract:

As a requirement of photovoltaic systems market, the project proposes widening the range of products and services offered by operators/developers plants and PV systems. Maintaining market for photovoltaic products and services is a goal of the entity (ICPE-SA) in business development perspective.

An important element of quality services aimed at testing equipment and photovoltaic components is the traceability of measurements and obtain reliable results in these tests. Therefore, maintaining reliable infrastructure at a level appropriate tests and validations in relation to references held by UVT is an important goal for the project.

The development of ties between the ICPE-SA specialists and researchers, students, master, doctoral students at UVT provides to industry and market in which it operates ICPE-SA, an ideal selection for future specialists in this field.

The main project objectives are:

1. Optimizing functional characterization systems in the endowment entity.

2. Develop methodologies for monitoring and testing of PV applications, according to industry standards.

3. Define portfolio of technical support services that ICPE- SA will provide producers of energy from photovoltaic.

In this regard it has been identified the following needs:

1. Preliminary assessment of the performance of photovoltaic modules under the conditions of standard operating compliance required for issuing bulletins specified by the manufacturer of PV modules.

2. Evaluation functionality during installation.

3. Operational evaluation phase.

Specific models are needed for processing quantities purchased, using characterization equipment of generators and PV installations designed to highlight defects or malfunctions regimes.

Abstract:

The project aims to achieve three prototypes of autonomous robotic systems. Prototype 1: wheelchair for elderly and people with severe and light disabilities. It is designed as a mobile robot (autonomous system) with two driving wheels and two free wheels (2DW/2FW), with a control structure based on advanced nonlinear techniques (sliding-mode and backstepping) and a structure for navigation and obstacle avoidance based on the combination between face and eye video-biometric system and a laser system and that can assist people with severe neuro-loco motor disabilities, people with light disabilities or elderly. This prototype is already called for trials and experiments to emergency hospitals from Galati and Targoviste, departments: intensive care unit, orthopaedics and neurology. Video-biometric system consists of two high-resolution cameras to monitor all person's face and eye biometric features. Since the control and navigation structure is novelty and originality in the field, it is considered patenting Prototype 1. Prototype 2 is designed as autonomous robotic system with two driving wheels and one or two free wheels (2DW/1FW or 2DW/2FW), with a remote control system based on advanced nonlinear techniques (sliding-mode and backstepping) and a navigation and obstacle avoidance structure based on ultrasound and laser. The mobile platform is equipped with a 6-DOF manipulator whose remote control and positioning system are based on nonlinear sliding-mode techniques and visual servoing. This prototype is able to handle and transport small medium and large weights, and is designed to operate in collaborative regime for servicing flexible assembly and processing lines to make them reversible, i.e. enabling disassembly or reprocessing, respectively. Disassembly and reprocessing will trigger when the final product does not meet quality requirements for reuse or reprocessing to be brought to the required quality parameters. Prototype 2, with 2DW/1DW and/or 2DW/1FW mobile platforms, equipped with robotic manipulator is already required to be integrated into body assembly lines of the car models Dacia Logan and Sandero at automotive company "DACIA-RENAULT" Pitesti. Integration Prototype 2 as autonomous robotic system equipped with manipulator into flexible manufacturing lines, in order to make them efficient, balanced and reversible, is for the first time in the field. The Prototype 3 is designed as an autonomous vehicle with four driving and steering (4DW/SW) multidirectional wheels, able to run on any type of road. Its control system is based on advanced nonlinear techniques (sliding-mode and backstepping) having the navigation and obstacle avoidance based on laser system. This autonomous vehicle is equipped with a 6-DOF robotic manipulator, able to carry and handle large loads and weights. It is designed for handling, transport and towing operations, indoor and outdoor, into manufacturing processes in metallurgy ("ARCELOR MITTAL" Galati-department of crowding raw materials, "VAE APCAROM" Buzau-handling, towing, and transport rails to/from annealing ovens), in ceramics ("CERSANIT" Roman-traction, transport and handling sanitary ceramics between ovens and drying stations) and in glass ("STICLA" Avrig-transport and handling large sheets of glass between the ovens and drying stations). Prototype 3 conceived as autonomous robotic vehicle designed to operate multidirectional on heavy conditions of road and loads, is a premier in the field of robotic systems.

Abstract:

The project InDeSEn has as main goal the optimisation of energy generation and load in a power system with distributed power from renewable energy resources (DP-RES), by designing and implementation an inteligent informatic platform for monitoring, forecasting and control.

The added value of the project consist to create and implement an intelligent decision support system (INDES) for the low voltage (LV) grid with DP-RES . It integrates decision theory and artificial intelligence concepts in monitoring, supervising, forecasting and control actions. INDES allows customers: to control electricity consumption of the used devices, to reduce their monthly bills, carbon emissions, energy demand during peak periods and to use more efficient the energy from RES. The application will be accessible to users anytime, providing both information for general use and technical information. The INDES, web interfaced, will be validated on an experimental model of LV grid with DP-RES.

The inovative software tool expressing the complexity of the proposed solution is gived by the integration of artificial intelligence in load and produced energy from RES forecasting.

The consortium includes Valahia University of Targoviste, Advanced Technology Systems company and Polytechnic University of Bucharest.

Abstract:

The main idea of the project, launched for the first time, is the advanced control and balancing reversible manufacturing lines (lines performing both,assembling and disassembling) using wheeled mobile robots,equipped with robotic manipulators. It proposes a new approach to manufacturing flow optimization problem:aggregation problems at levels of continuous and discrete event in a hybrid system. The control objectives are: balancing flows of reversible manufacturing by developing optimal loading strategy workstations,advanced robotic systems control for precision movement with a certain path, for variable load, but in temporal windows,ordering the manufacturing correlated with dynamic control of the queue and the control of robotic systems as continuously nonlinear autonomous system. Hybrid system will be structured in two subsystems:the discrete event system and the continuous system for advanced robotic control to ensure robust functioning of balancing,assembling and disassembling. The study will focus on defining a hybrid control system which automatically synthesizes a hybrid supervisor. Modeling, balancing and control of reversible manufacturing lines,serviced by robotic manipulators mounted on wheeled mobile robots,is addressed for the first time and is an absolute novelty part of the proposal. Making reversible and controlling an assembling line, in order to perform disassembling, served by wheeled mobile robots equipped with robotic manipulators, is also a premiere.
