SBL analysis was commonly applied for controller stabilization problems. However, we use SBL analysis for the reduction of high order linear time invariant system models to second-order approximate models to facilitate analytical design of closed loop PID control systems. The PID design is implemented by a multiple pole placement strategy which enforces the control system had real poles with a desired time constant specification. Illustrative design examples are presented for the analytical PID design of high-order plant models by means of second-order SBL model approximations.","PeriodicalId":369687,"journal":{"name":"2015 9th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131035119","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}

These types of motors are easier to manufacture compared to conventional caged rotor induction machines (CRIM). In addition to that their high material integrity and high thermal properties makes them suitable to be used for high-pressure and high-speed drive applications. This paper proposes a new innovative rotor type for SRIM using in high-speed drive applications. This rotor type consists of hybrid construction of axially slitted and coated solid rotor structures and it is named as Shielded Axially Slitted Solid Rotor Induction Machine (SASSRIM) by the authors. In order to obtain performance characteristics of the novel designed rotor type, transient magnetic model is analyzed by finite element method (FEM). Finite Element Analysis (FEA) results show that rated output torque of SASSRIM is higher and more stable than other solid rotor structures. The brand new design also decreases the total losses, thereby making it more efficient than other conventional solid rotor designs.","PeriodicalId":369687,"journal":{"name":"2015 9th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127462008","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}

Various sensors as laser, sonar or camera have been used for this process. Two sensors as a camera and laser are employed together in some studies in literature. Camera based studies propose different methods using single camera or two cameras. In this study, the distance between the cameras and the colored object (red colored object is accepted in this study) is calculated in pixels and cm using two cameras situated in the same axis. In this proposed study, the images taken from the left and right cameras are preprocessed first. Then, the objects in the environment are determined.

The increase in the number of EVs, while providing green and inexpensive solutions to transportation needs, may cause constraints on the operation of the utility grid that should be investigated. In this paper, the real user driving information is collected from individual data tracking devices of passenger vehicle owners instead of assuming randomly distributed trip characteristics. The collected trip data are first analyzed to generate a statistical model of the trip characteristics in terms of home arrival times and state of charge (SOC) levels. The resulting model is then used to simulate and analyze the impact of EV integration in a real grid with different EV penetration levels. For this, real distribution transformer data provided by Başkent Electric Distribution Co. is used. The proposed method produces more realistic results in comparison to the studies assuming random scenarios.","PeriodicalId":369687,"journal":{"name":"2015 9th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116990211","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}

PWM transform the information in the amplitude of a bounded input signal into the pulse width output signal, without suffering from quantization noise. The frequency of the output signal is usually constant. In this paper the new PWM system with frequency changing (PWMF) is described. In PWMF the pulse width and also frequency is changed, therefore 2 independents information are simultaneously transmitted, and PWM and frequency modulation (FM) are simultaneously used. But such system needs fast demodulator separately for PWM and FM. The circuit for fast demodulation of PWMF signal is also described and measuring results are presented.

The penetration of photovoltaics (PVs) in distribution networks would definitely affect the power system problems such as capacitor installation strategies. Therefore, an optimal procedure is proposed herein which investigates the simultaneous placement of PV-based distributed generations (DGs) and capacitors taking into account different load curves, electricity prices, and hourly photovoltaic power generation in a daily basis. Moreover, the seasonal changes in daily load and renewable generations have been also modeled as an impressive factor in the founded methodology. The optimization procedure is handled with genetic algorithm (GA) and tested on IEEE 69-bus radial distribution test system aiming at minimization of energy losses costs. Focusing on numerical studies, the distributed reactive support capability of PVs in altering the capacitor placement solutions has been discussed in depth to certify their substantial effect. The obtained results are encouraging.","PeriodicalId":369687,"journal":{"name":"2015 9th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126176476","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}

In this study, we propose a neural network (NN) based approach to demodulate the transmitted signal over fading channels. The novelty of the resulting scheme lies in the combination of channel estimation, equalization, and demodulation procedures in a single NN structure. We assess the performance of the proposed receiver for Rayleigh fading channels. It is demonstrated that the Rayleigh theoretical bound may be achieved by the proposed receiver if the frame structure has a sufficient pilot duration in the training mode. It is also shown that the proposed receiver is robust for low SNR cases.","PeriodicalId":369687,"journal":{"name":"2015 9th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132102481","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}
