It should be noted that in the case of the classic inverted pendulum its upright position is held by changing position of the cart relative to the ground. In contrast, man is not moving relative to the ground maintains its position through changes in muscle tension.. Projection of the center of gravity is located on the ground in the contour of the human feet.

The transform is the exact definition of the Discrete Radon transform. Despite of the simplicity of its mathematics, this transform is a really computationally intensive procedure. The purpose of this paper is to introduce algorithms based on the Mojette Transform that the research group (composed from three university members) developed in recent years. These algorithms are mainly made for purposes of image processing, which are increasingly popular in fields where the real-time operation is of utmost importance. This is why was developed an algorithm that can reach nearly the runtime of real-time image processing needs. For the implementation the LabVIEW (trademark of National Instruments) was used. The benefits of using LabVIEW are explained, and the details of the new algorithm, that is different from the previous implementations presented in [12] and [13], are given. Finally partial results of the implementation of the proposed algorithms are discussed.","PeriodicalId":105920,"journal":{"name":"Proceedings of the 2014 15th International Carpathian Control Conference (ICCC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132999741","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}

Design and tuning of proposed controllers is performed by algebraic tools where transfer functions are regarded as elements of the field of fractions associated with an appropriate ring according to the desired properties. The emphasis of designed autotuners is laid to SISO systems with time delays. Autotuners then represent a combination of a relay feedback identification test and some control design method. Within the scope of this contribution, models with up to three parameters are estimated by means of a single asymmetrical relay experiment. Then a stable low order transfer function with a time delay term is identified. Then, the control design is based on the ring of proper and stable rational functions (RPS). Controller parameters are derived through a general solution of a linear Diophantine equation and a generalization for a two degree of freedom (2DOF) control structure is performed. A final controller can be tuned by a scalar real parameter m>0. The presented philosophy covers a generalization of PID controllers. The analytical simple rule is derived for aperiodic control response in the RPS case. Autotuning principles then combine asymmetrical relay feedback tests with a control synthesis. A Matlab program for automatic design and simulation was developed and various simulations performed and analyzed.","PeriodicalId":105920,"journal":{"name":"Proceedings of the 2014 15th International Carpathian Control Conference (ICCC)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133176932","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}

For moisture evaluation of combusted fuel, several formula were previously proposed. In the investigations reported in the paper they have been examined which of them is the most suitable for the moisture inference gained in small-scale biomass fired boilers. In the proposed neural network based on two neurons, the back propagation method has been used for derivation of the adaptation rule. Results of the evaluation are based on real data obtained in the experiments carried on a prototype 100 kW of Fiedler biomass boiler. The boiler has a special instrumentation making possible to check correctness of obtained results not only in the values of moisture but also in the other parameters occurring in the used formula.","PeriodicalId":105920,"journal":{"name":"Proceedings of the 2014 15th International Carpathian Control Conference (ICCC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133734139","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 most common solution is evidence in a paper form, usually in a book at the entry point. More recently, this problem is solved by using ERP systems, where information is being recorded to the database. The main disadvantage of these options is the necessity of hand-writing, while intentional or unintentional errors can occur. In this paper we describe the first steps in project of design of system ensuring improved security processes, optimization and automatic process control for entrances and exits to and from the private parking areas of business entities. Goal of this project is to modernize the existing system and design of the new solutions for identification and registration of vehicles based on RFID technology. Radio frequency identification technology, due to contactless way of identification of items and objects, provides better and safer solutions, especially in conjunction with a camera system. Double identification can provide higher level of precision and also ensures the reliability of identification in comparison with the camera system alone, where only optical vehicle registration plate recognition is utilized. Our proposed system involves the use of automatic identification based on both RFID and optical camera system recognition at the entrance/exit to/from the areas. Cars of employees and regular suppliers/customers will be equipped by RFID tags, which will be firmly placed on the vehicle. The proposed system does not remove the need of the security presence of at the gatehouse object, however, reduces the potential error rate, cheating with self-printed plates and also increases the efficiency of processes and prevents downtime.","PeriodicalId":105920,"journal":{"name":"Proceedings of the 2014 15th International Carpathian Control Conference (ICCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122289061","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}
