There are exchanges of power among different parts of power systems involved in its operation. Hence, we investigate the effect of bidirectional coupling between two Single Machine Infinite Bus (SMIB) power systems to study its dynamic behavior. The dynamics of these coupled systems is strongly influenced by variation in coupling strength. The uncoupled systems which are initially in chaotic state can be anti synchronised between each other by suitable choice of coupling form and optimum coupling strength. It is observed that stronger coupling can drive chaotic systems back to periodic state.","PeriodicalId":443423,"journal":{"name":"2017 International Conference on Circuits, Controls, and Communications (CCUBE)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116726286","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}

A novel square resonator integrated with inter-digital coupling on both sides plays a key role in this filter design. Design and EM Simulation of the UWB filter's characteristics are discussed in this work. The proposed UWB filter produces tremendous bandwidth ranges from 2.3 GHz to 8 GHz. It also exhibit out band characteristics which meets the FCC's requirement. The simulation study of the projected filter is executed by electromagnetic tool. The filter evaluation parameters like return loss, insertion loss, phase and group delay are obtained and their responses are analyzed. The complete size measurement of the filter is achieved to be 39mm×3.2mm×1.6mm on accounting the above features. The calculated bandwidth ratio with respect to center frequency of the filter is obtained about 115%. The performance parameter results shows the filter's return loss (S11) and insertion loss (S21) are -41 dB and -2 dB respectively.","PeriodicalId":443423,"journal":{"name":"2017 International Conference on Circuits, Controls, and Communications (CCUBE)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126852312","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 very important to monitor various health parameters of the aircraft in order to ensure safety of passengers, crew and operators and to improve reliability of aircraft. Even as the aerospace community is working on multiple technologies like EHM, SHM, AHM and IVHM to monitor health parameters, there are challenges in selecting and placing the sensors optimally and establishing seamless communication between different subsystem monitoring units. This requires increased number of sensors and with the existing wired network in the aircraft, deploying and managing a scalable sensor network becomes more complicated. It is proposed to develop WSN onboard aircraft to simplify configurability and maintainability for a scalable network. Developing new WSN comes with design challenges for selection of topologies, frequency allocation for wireless nodes and meeting the performance metrics in terms of network throughput, system latency and reliable data. Since performance metrics depends on the traffic characteristics, a mathematical model for network traffic analysis for the proposed WSN is presented. Priority Queueing theory has been used in the model to handle different priority levels of multi-typed and multi-rated sensor data in an avionics network. Both preemptive and non-preemptive priority handling policies are used to define mathematical expressions for network traffic. The policies enable comparative analysis of network performance in terms of qualifying system response to low priority data in presence of those belonging to high priority class. The model is applied to a representative network with 6 sensors of different priority levels and variable data rates to assess QoS parameters of the network, in specific (i) Average system response and (ii) Waiting time. The network simulation platform presented in the paper serves as a tool to assess feasibility of MAC protocol selection for different scenarios in wireless avionic communications.","PeriodicalId":443423,"journal":{"name":"2017 International Conference on Circuits, Controls, and Communications (CCUBE)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123081926","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 work investigates whether a discrete time periodic controller can provide a superior robustness in controlling of DC-DC boost converter operating in continuous conduction mode (CCM) by virtue of its loop-zero placement capability. The problem considered is in the context of robust control of non-minimum phase (NMP) system, i.e system with unstable zero in its dynamics. The present works investigates whether it is possible to relocate non-minimum phase zero of fixed frequency boost converter operating in CCM. In this respect a 2-DOF, 2- Periodic controller is designed, that employs a systematic 2-stage algorithm involving linear algebraic steps, to verify the result. The effectiveness of the proposed controller is then evaluated and the improvements in transient behavior along with robustness are shown via simulation results.","PeriodicalId":443423,"journal":{"name":"2017 International Conference on Circuits, Controls, and Communications (CCUBE)","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115858477","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}
