A simplified vibration model of the Stirling engine generator is justified on the basis that the response of the proposed model is verified to match well that of the real one. Two active control techniques are discussed and analyzed in the time and frequency domains. The first control strategy is based on a Feed-forward zero-placement control whereas the second one is linear quadratic (LQ) optimal control and state observer.","PeriodicalId":430829,"journal":{"name":"Proceedings of the 16th International Conference on Mechatronics - Mechatronika 2014","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121552782","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}

Presented method is based on developing new algorithms for the current parking assistant electronic control units (ECUs) using the ultrasonic sensors. Key idea is to estimate the length of the trailer shaft (axle to coupling length), and the angle between the car and trailer. With those the control for the steering of the car to backup the trailer in the desired direction can be designed.","PeriodicalId":430829,"journal":{"name":"Proceedings of the 16th International Conference on Mechatronics - Mechatronika 2014","volume":"45 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":"127402929","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}

To identify its dynamic behavior an experimental setup has been developed that enables to measure data of the system input (armature voltage) and output (current and rotor speed). Generally, the identification methods can be classified as parametric and non-parametric. We use a non-parametric method (black box). A recurrent neural network was used and the Nonlinear AutoRegressive network with eXogenous inputs network (NARX) has been selected. Parallel architectures have been used in training the NARX network. The scaled conjugate gradient training algorithm, using the first and second derivatives of error to train the network to minimize the error function, has been selected. The network architecture which has been used to create the dynamic model of the motor consists of three hidden layers, a single input neuron, and two output neurons. The modeled and measured normalized data were compared with good conformity.","PeriodicalId":430829,"journal":{"name":"Proceedings of the 16th International Conference on Mechatronics - Mechatronika 2014","volume":"140 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":"127501685","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 sensor is designed to have a T-shape structure, so that the rope can cross over the sensor without any damage during measurement. In the process of measuring parachute haulage cable, it requires strict requests on the shape and structure of the sensor. The shape and structure of the sensor may have impacts on the measurement or even disabled measurement. So a wireless passive operating mode of measurement is proposed. Surface acoustic wave which is a wireless passive object is used at sensor surface functioning as both sensor element and signal transmission medium. The change of tension in a rope is converted into the change of stress in such sensor, leading to the change of resonant frequency of the surface acoustic wave device, which can be detected by the reader. Simulation results show that the sensor has better sensitivity and linearity.","PeriodicalId":430829,"journal":{"name":"Proceedings of the 16th International Conference on Mechatronics - Mechatronika 2014","volume":"192 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":"116726976","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}

Most of currently used solutions are realized with rotational motor and crank mechanism or with application based on “Wagner hammer” principle. Rotational drive is limited to slightly adjust velocity profile of the needle during one operating cycle and also the complex construction didn't allow easy disinfection processes. System based on “Wagner hammer” is widely used but its most significant disadvantage is instability of its mechanical parameters which leads to frequent adjusting of the system. The innovated solution is based on electromechanical actuator with enforced (controlled) dynamics, which eliminate all mentioned disadvantages of mechanical solutions. The paper describes design of electric drivers of electromagnetic actuators and the control principles are explained too. Some practical experience gained during realization of the prototype together with measured results are discussed.","PeriodicalId":430829,"journal":{"name":"Proceedings of the 16th International Conference on Mechatronics - Mechatronika 2014","volume":"11 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":"129675317","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}

Laboratory urine culture is the standard detection method which is expensive and time consuming. This paper studies the possibility of using a capacitive sensor to diagnose UTIs. Experimental tests were carried out to investigate the touch sensor's response to artificially prepared E.coli sample. The capacitive touch sensor gave a consistent result that could be used to design a portable diagnostic device for early detection of UTIs. An exponential response was observed to increasing volume (up to 100 microliter) and E.coli presence in the sample. When the volume reached 100 microliter, the capacitance in average RAW Count Difference value became constant. Urine sample mixed with liquid E. coli gave the highest capacitance change (in average RAW Count Difference value) and the sensitivity at 100 microliter was found to be 22 counts per picofarad (pF).","PeriodicalId":430829,"journal":{"name":"Proceedings of the 16th International Conference on Mechatronics - Mechatronika 2014","volume":"60 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":"128920678","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}

This is caused by the fact that electrical quantities cannot be measured in the rotor cage. In addition there is proved in the literature, that classical Γ-network includes too much freedom degrees (i.e. 4), therefore it cannot be identified unequivocally. On the other hand, the G-network includes only 3 freedom degrees, and, based on this fact, it is identifiable absolutely unequivocally. Therefore there are derived equations for the exact mutual transformation of the parameters of individual substituting circuits (T-, Γ-, and inverse Ψ-network).","PeriodicalId":430829,"journal":{"name":"Proceedings of the 16th International Conference on Mechatronics - Mechatronika 2014","volume":"38 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":"124135087","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}
