Strategy Extraction for Mobile Embedded Control Systems Apply the Multi-agent Technology

Mobile embedded systems belong among the typical applications of the distributed systems control in real time. An example of a mobile control system is the robotic system. The proposal and realization of such distributed control system represents a demanding and complex task of real time control. In the process of robot soccer game application extensive data is accumulated. A reduction of such data is a possible win in game strategy. SVD decomposition of matrixes is used in data reduction.

Strategy Description for Mobile Embedded Control Systems Exploiting the Multi-agent Technology

Mobile embedded systems are a part of standard applications of distributed system control in real time. An example of a mobile control system is the robotic system. The software part of a distributed control system is realized by decision making and executive agents. The algorithm of agents cooperation was proposed with the control agent on a higher level. The algorithms for agents realized in robots are the same. Real---time dynamic simple strategy description and strategy learning possibility based on game observation is important for discovering opponents strategies and searching for tactical group movements, simulation and synthesis of suitable counter-strategies. For the improvement of game strategy, we are developing an abstract description of the game and propose ways to use this description (e.g. for learning rules and adapting team strategies to every single opponent).

Accumulation system of electric vehicle and its secondary exploitation

With the constantly evolving technology for the production of electricity and heat production cost of such systems are constantly decreasing. With the growing awareness about human behavior and their impact on the environment are constantly looking for new measures to reduce this impact. The technologies that do not pollute the environment after their production are undoubtedly alternative energy sources and electric vehicles. In combination with awareness of each of us, we can create a system providing both electrical and thermal energy, together with traveling. In the article below outlines the design concept of the electric connection electric vehicle to the electricity system of the house, which is both electrically and thermally independent.

Application of Multi-agents in Control of Hydrogen Powered Car to Optimize Fuel Consumption

Mobile embedded systems belong among typical applications of the distributed systems control in real time. An example of a mobile control system is the hydrogen powered prototype car control system. The design and realization of such distributed control system represent demanding and complex task of real time control for minimization of race car fuel consumption. The design and realization of distributed control system, mention above, is prepared for testing as a complex laboratory task. The control system software uses multi-agent technology with dynamic mutual negotiation of mobile system parts. The real hardware and software model is also important motivation for extended study.

The Use an Electric Vehicle as a Power Source

Electric cars are becoming a serious competition for the common artificial fuel driven cars in small city agglomerates and short distances. With the new developments on the field of state-of-art accumulators, electric cars are becoming much more that just a single use items, but can serve a number of roles. One of them is possibility to use excessive energy stored in the batteries and its rerouting from the car to other systems (such as offices, family houses, lighting etc.). This brief article is making a suggestion on usage and lifecycle of traction batteries, interconnection of the house and its electric car. Additionally, logic and control of such a transfer processes is put to the test for conclusion, that the electric car can be used as both the mean of transportation as well as energy source while in the meantime its primary function is not dampened at all.

Experiences with the project-oriented learning

The R&D Team SAES (Systems of the Alternate Energy Sources) is a group of teachers, technicians and research and development workers focussing on issues related to sensors, measuring, controlling, and intelligent management of systems using alternative energy sources. The team manages a number of learning and research laboratories and participates in activities by three research and development workplaces. One of the main activities is an active participation in learning process. Team members guarantee and conduct lecturing in a number of subjects in an active way. The introduction of project-oriented learning allowed for the student motivation leading to deeper studies and it put the theory closer to real applications. This education construct and its results have been currently used for the start and maintenance of cooperation between the university and secondary schools. It closely shows activities at the university to secondary school students and prepares them for their future studies.

A measuring system for monitoring error artefacts in photovoltaic solar cells by the electroluminescence method

Abstract Photovoltaic system for the last four years spread among the general public are now due to media reports understood very negatively in the Czech Republic. It is important to note that the actual photovoltaic systems are a breakthrough technology and negatives stand out thanks to a govern the Czech Republic and their ignorance and short-term vision. Photovoltaic solar systems belong to the group of alternative energy sources. The lifetime of these energy sources is related to a large extent with the production quality and the ability to detect errors technology manufacturers. In the article below is one of the best detection method that enables the detection of defects in the production of photovoltaic cells. This method is called electroluminescence.

TRT system for heat pumps design

Abstract The paper deals with problematic of Thermal Response Test (TRT) system. The correct design of borehole heat exchangers for ground source heat pumps and the knowledge of rock massive thermal properties is paramount. For small heat pumps systems these parameters are estimated. However, for larger objects the thermal conductivity should be measured on site. Thermal Response Test is an useful tool for thermal conductivity estimation. This test is instrumental to find out a response of rock massive in which a heat pump might be installed. The paper describes basic principles of TRT and its utilization for heat pump boreholes design.

Embedded Remote Measurement and Control System Apply GSM

Abstract In large distributed control systems or in large information systems still more often the wireless communication with remote objects which are the integral part of these systems is used. The second sphere of the wireless communication utilization is represented by the mobile objects in the control or information system. In the large systems we can utilize, with advantage, the communication which will be provided by the GSM technique. Good covering by signal in case of GSM enables the building up of measuring and control systems where the communication can run also in the demanding terrain. The given application describes the distributed system oftemperatures measuring in prospect holes on mine dumps.

Modeling and simulation for 1.2 kW PEM fuel cell power generation of isolated load conditions

The PEM Fuel cell are deliberated as one of the almost favourable devices for isolated/grid connected distributed generations (DGs) due to its cleanliness, modularity and higher potential capability. This paper presents the modeling and simulation for 1.2 kW PEM Fuel Cell Power Generation of Isolated Load conditions. The proposed scheme consists of a Fuel rate selector, Fuel rate regulator, Fuel cell stack, Boost converter, Filter circuit and Load. The PEM Fuel cell model includes the dynamics of reactant flow, membrane resistance, stack efficiency and capacitance as well as steady-state equation. Modeling and simulation of the PEM fuel cell power generation are carried out by Matlab software. The variation of load corresponds to the output voltage, current, and fuel cell flows rates are examined. The present modeling and simulation results are validated with sample experiments results are conducted in VSB-Technical University of Ostrava.
