DC brushless motors are widely adopted for their simplicity of control, even in sensorless configuration, and their high torque density. On the other hand, induction motors are very economical due to the absence of permanent magnets; for the same reason they can easily be driven in the flux-weakening region to attain a wide speed range. Nevertheles...

Usage of sustainable energy is a key factor for solving future environmental issues. The purpose of the project SustEner is to modernize sustainable electrical energy vocational training by enhancing existing or establishing new training methods in enterprises and education. This paper presents the SustEner module power management techniques in hybrid electrical cars. Increasing market demand for hybrid electric vehicle (HEV) leads to a higher effort on training and education of high qualified engineers in this field. Beside the development and design of different HEV components also the interaction and efficiency of the entire system is a key factor. Understanding the power flow from one component to the other improves the ability of developing high efficiency HEV. Online teaching tools provide the possibility of teaching complex technical problem in an easy way and with high approval. Thus an interactive simulation tool was developed teaching power management techniques for HEV. In the following an interactive online tool is presented based on a MATLAB/Simulink HEV model enabling configuration of a HEV and efficiency analysis for a specific drive cycle.
... Remote hardware experiments are adapted in such a way that they can be accessed from the web, which enables distance sharing of the experiment by various individuals and/or institutions. Manuscript Currently we can find numerous solutions for remote controlled experiments in various fields of practical education and also there are numerous projects running whose developments have been presented at special conferences, e.g. in [3], [4] and at special sessions of scientific conferences [1], [8], [9], [11]- [14], etc. ...
This paper presents the organisation and the technical structure of a remote controlled laboratory in the field of high dynamic drives and motion control. It is part of the PEMCWebLab project with the goal of providing students with practical experience on real systems in the field of power electronics and drives. The whole project is based on clear targets and leading ideas. A set of experiments can be remotely performed on a real system to stepwise identify a two axes positioning system and to design different cascaded control loops. Each single experiment is defined by its goals, the content of how to achieve them, and a verification of the results as well as the achieved learning outcomes. After a short description of the PEMCWebLab project, the structure of the remote control is presented together with the hardware applied. One important point is error handling as real machines and power electronics are applied. Finally, a selection of experiments is presented to show the graphical user interface and the sequence of the laboratory.

The paper deals with basic philosophy and structure of remote controlled laboratory for experimentation in electrical engineering. The laboratory collects experiments from fields of power electronics, electrical machines, electro-mechanical and motion control systems. The workbenches in the real laboratory are used over Internet. The real experiments of the remote controlled laboratory are placed at various universities. A special care is devoted to preparation of the learners to experimentation, including examining their knowledge before joining to the experiment. To have a feeling of participation in the experiment, except of the measurement data, also the signal from Web camera is transferred to a distance operator.

During the E-learning Distance Interactive Practical Education project, 13 partners from 11 European countries joined together to build a power engineering and motion control remote laboratory, which would offer 18 complete online courses with remote experiments and high-quality documentation, to students from the universities of all participating partners. The major benefit of this project is the possibility of sharing expensive equipment and lessening the burdens of technical and organizational problems. This paper outlines the project's goals, organization, and, as an example, realization of one of the project's modules. The described module is a mechatronics motion control course, which explains the most important aspects of motion control design, from modeling, simulations, control design, experimental validation, and comparison between various controllers. The technical solutions, educational strategy, and realization details are given for the module. The pilot testing of the module was performed to assess the module and find out what the students' personal attitude concerning e-learning and remote experiments. The results of testing are presented and discussed.
The paper deals with basic philosophy and structure of remote controlled laboratory for experimentation in electrical engineering. PEMCWebLab project provides the user with a practical experience in industrial electronics education. It is designed based on leading ideas and has clear targets. In this paper laboratory for the course motion control is introduced. First of all description of the system and then two assignments namely calibration of resolver and current control loop design explained. Goal of the experiment, content of the experiment and verification of the achieved learning outcomes is illustrated on the mentioned two examples.
This chapter is structured in sections covering three main issues. Section 2 reviews current trends in web-based medical teaching & learning with the emphasis on their efficiency, configurations and instructional methods. Web 2.0 is discussed separately in Section 3, demonstrating potential implementation of wikis and podcasting to make theoretical and pre-clinical subjects more attractive, but also pointing at controversies and pitfalls of this new technology in medical and healthcare contexts. In Section 4 the authors describe methods and procedures used to re-design a paediatric undergraduate curriculum in a European country (Czech Republic). The innovation of educational interventions was based on three cornerstones, ie. case-based reasoning, evidence-based medicine, and blended learning. The authors demonstrate all current arguments and opportunities to view medical education not as a sum of knowledge, but as a practical know-how. This approach should be supported by information and communication technologies, eg. development of e-learning portals. We are presenting the educational portal as a unique solution. The outcomes of the project including student feedback are presented as figures, graphs and verbatims. The section ends with a brief proposal for developers of case-based learning environment in medicine. The methods used to compile this chapter included brain-storming, literature review, deduction, curriculum re-design, web-portal development, qualitative analysis of attitudes, and statistical analysis.
