A DC-DC converter in most of the applications is controlled by a voltage mode or a current mode controller. The DC converters are employed to feed electric vehicles, telephone sets and civil invertors, or for induction motors and frequency control. In this regard, optimal exploitation of DC transformed by classical controllers has been a controversial issue in reputable journal publications. Due to their switching property included in their structure, DC-DC converters have a non-linear behavior and their controlling design is accompanied with complexities. However, by employing the average method, it is possible to simplify the system as a linear system and exploiting linear control methods. In this article, an attempt is made to control the buck converter by PI and PID controllers. By using PID controller and genetic algorithm, a new adaptive control method model is introduced. A Genetic algorithm is applied to discover the supreme values for PID controller's parameters within a short time period. The improvement of the current control response is the result of the simulation.","PeriodicalId":273802,"journal":{"name":"2013 10th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123748153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The test set feeds current periodically into the cable under testing. In on-cycle, the test set heats up the cable for at least 8 hours while in the off-cycle, it allows the cable to cool down for at least 16 hours until its conductor temperature is within 10 °C above the ambient temperature. The current that is fed into the cable during the on-cycle is to be recorded for 2 consecutive hours when the conductor temperature remains constant as per the insulation standard (IEC 60840-2004). The heat cycles test set has two separate current sources, which can be used independently. Programmable Logic Control (PLC) is used in controlling the operations of the test set, e.g. the two current sources can be programmed to work together, moreover, the number of testing cycles, feeding current, and also the resulted temperature of any on-cycle can be selected. In conclusion, the test set built as described, can perform its functions satisfyingly while accomplishing cost reduction. This is because an imported test set of the same kind is more expensive. Besides, a digital recorder is installed for recording temperature and current during testing. An acceptable error of 1.45% to -1.62% of the test set is obtained when undergone the calibration.","PeriodicalId":273802,"journal":{"name":"2013 10th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124032979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the most popular approaches to solve local obstacle avoidance is Dynamic Window approach. This approach is to search optimal control command of the robot in velocity space directly. The command which maximizes objective function is then selected as output command. In the original Dynamic Window approach, in order to avoid obstacles, it concerns only obstacles on robot's trajectory. Therefore, the robot might crash with some obstacles which are near the trajectory but not on the trajectory. Therefore, in this work, we propose field Dynamic Window approach (F-DWA) which objective function is modified to consider the obstacles near the trajectory as well. This can be done by the use of histogram grid representation of obstacles to estimate the crashing probability of the trajectory. The objective function of Dynamic Window approach also depends on the crashing probability as well as other traditional factors. To test the robustness of proposed algorithm, experiment in real world is conducted. The result is the robot can travel safer when it concerns near-trajectory obstacles.","PeriodicalId":273802,"journal":{"name":"2013 10th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129197484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From the measurement it is shown that plasma antenna is just effective as metal antennas and it can work as a transmitter and receiver signals. Plasma antenna consists of glass tube filled with some neutral gases such as Argon. In the experiment a commercially available fluorescent tube function as a plasma antenna, with length 0.31m (l) and diameter 0.031m (r) is used as the plasma antenna. The tube was energized by 12 V DC, and 0.8 A current, which is provided by a standard DC power supply. The DC power supply was connected to DC ballast before directed to both electrodes of the fluorescent tube. A Vector Network Analyzer (VNA) is connected to coupling sleeve. This simulation is performed by using the simulation software Computer Simulation Technology (CST) Microwave Studio. The frequency target range 700MHz until 900MHz which is this frequency can apply in ultra high frequency (UHF).","PeriodicalId":273802,"journal":{"name":"2013 10th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116991468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
