This type of control provides direct current control and sufficient control of output voltage. The proposed control strategy is based on second order general integrator phase locked loop (SOGI-PLL), which is used for trolley voltage synchronization. In this case SOGI-PLL evaluates voltage position, amplitude and frequency. These data are used for precise and robust current control, which uses PR controller. The behavior of designed control and SOGI-PLL synchronization is analyzed by both simulations and experiments made on developed 1.5 kW laboratory prototype.","PeriodicalId":430829,"journal":{"name":"Proceedings of the 16th International Conference on Mechatronics - Mechatronika 2014","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126206206","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 shape of the work coil was matched to horseshoe heating. Required simplicity and robustness of the device excludes the use of water cooled work coil (made of copper tube) which is mainly used in the applications of induction heating. A HF Litz-wire was used in the construction of the work coil in our solution. A non-tradition conception of the input rectifier with a low DC-link capacity is used. This way a sufficiently high power factor can be achieved without any additional PFC circuit. A double acting inverter using a MOS-FET half-bridge is used for exciting the series resonant tank. The system description of the designed induction heater is presented including some important details.","PeriodicalId":430829,"journal":{"name":"Proceedings of the 16th International Conference on Mechatronics - Mechatronika 2014","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127422855","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}

Modeling and simulation of a thermoelectric Energy Harvesting System for control design purposes 以控制设计为目的的热电能量收集系统建模与仿真

The overall system is modeled and simulated in the component-oriented environment Modelica®/Dymola®. The model is used to analyze and verify different control concepts to maximize the power output of the EHS. The TEGs used are devices consisting of thermoelectric material that exploit a temperature difference to generate electrical energy due to the Seebeck Effect. By means of TEGs, the overall energy efficiency of combustion processes can be improved by converting a portion of the remaining waste heat into electric power. For this purpose, TEG pairs (pTEGs) are installed on the exhaust pipe alongside the exhaust gas stream. However, with the exhaust gas losing heat in downstream direction, the final pTEG may lower the overall EHS performance due to their electrical resistance. With the help of the presented simulation model, it is possible to remove detrimental pTEGs from the EHS. This removal may happen either statically, i.e. in the design phase, or dynamically, i.e. by finding the ideal instant of time to disconnect and to revive them during operation.","PeriodicalId":430829,"journal":{"name":"Proceedings of the 16th International Conference on Mechatronics - Mechatronika 2014","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130602713","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}

It is based on the data obtained from an Inertial Measurement Unit (IMU), which is placed in the robot's torso. IMU includes accelerometer and gyroscope. Relying on these data, we propose the algorithm that maintains stability of the robot, while the support platform tilts. Our experimental object was a small humanoid robot M-Bot, which was built by authors and is shortly described in this paper. To determine the orientation of the robot we developed a digital filter. To maintain the static stability we decided to implement a controller based on the position of the Center of Mass (COM) projection on the ground plane. To adjust COM position we use ankle and hip strategy. These strategies provide stabilization only in one plane. To improve side stability we propose the leg adjustments. This algorithm detects the possibility of exceeding outer boundary of the foot by COM and adjusts configuration of the leg to prevent against falling to one side. The developed algorithms were fully tested on a real construction of M-bot robot. Experimental results demonstrated that our implementation successfully stabilizes a humanoid robot.","PeriodicalId":430829,"journal":{"name":"Proceedings of the 16th International Conference on Mechatronics - Mechatronika 2014","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128158176","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}

Traditionally commonly used linear control model can not adequately represent the intermitted pulse-like qualities in real-world steering angle measurements. Therefore, based on an alternative `pulse control model' of steering control for vehicle lane keeping, steering angle measurements can be decomposed into a combination of ramps (global curvatures) and pulses (local corrections). Measurement trend is extracted through empirical mode decomposition (EMD) technique, where principal component analysis (PCA) is applied as a supplement to quantify the component contribution. Reversal points are found from the extracted pulses by further selections of conditional rules, which then reveals a pattern which is useful to test the overall model validation.","PeriodicalId":430829,"journal":{"name":"Proceedings of the 16th International Conference on Mechatronics - Mechatronika 2014","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129012431","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}
