The objective is to station the aerostat at a desired position anywhere into and on a hemisphere of an allocated radius with constraints applied on tether lengths and controller gains. Optimization is performed to find an optimal set of PID controller gains in order to minimize the total error over the entire trajectory. Two schemes for integral error calculation are proposed in this work. The first scheme implements historical values of the error resulting in adding an unnecessary bias to the output. This is overcome by the use of an error history over a finite horizon when calculating the integral error. Improved performance of the controller with faster convergence for position tracking is achieved by the implementation of the second scheme. In the first scheme, a settling time of approximately 72 s is achieved which is improved to approximately 40 s with the implementation of the second scheme. The conditions for position change of the aerostat are discussed. The results depict a three- dimensional space trajectory of the solar-powered aerostat being relocated to a cloudless new position for reliable solar power generation.","PeriodicalId":292408,"journal":{"name":"2019 International Conference on Nascent Technologies in Engineering (ICNTE)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126501149","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}

Also, optical communication is suitable for high bandwidth applications and gaining popularity over any other wired media which are currently used with FPGA implementations. This proposed research work is to focus on achieving optical fiber link with Xilinx Gigabit transceiver block for data rates of over 3.125 Gbps transmitted serially. The optical digital link will be established between two FPGA boards which are Spartan 6 Series SP605 boards which can be coupled to optical transceiver modules known as SFP. The basic GTP MAC wrapper core from Xilinx is being used as base for data transmission and reception. GTP performance is validated with the help of Xilinx bit error test known as IBERT. The results of the IBERT test are observed and calculated using Chip-Scope-Pro analyzer to obtain the faults in connections, defects in medium, bit error ratio and bit error detection during transmission and reception. Various ports in each GTP tile required for clock, reset, encoding, decoding, serialization, deserialization, error correction, polarity control, pattern checking, etc are used to run a code which will enable the actual transmission and reception of information bits with high data rate with very low bit error rate.","PeriodicalId":292408,"journal":{"name":"2019 International Conference on Nascent Technologies in Engineering (ICNTE)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126724517","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}

Several functions e.g. pure sinusoidal, saw-tooth, square, quasi-square and triangular waveforms have been generated over a wide frequency range as per applications. By utilizing the unique architecture and excellent processing capabilities of Microcontroller 8051 including its interfacing with Digital to Analog Converter, the hardware is minimized to a great extent and the desired output wave shapes are digitally controlled to achieve the required waveforms. The control instructions have been written in KEIL software. The Personal Computer based experimental circuit operation has been designed incorporating languages translators via compilation and assembly process. A Microcontroller based system is found to be numerically attractive since it offers increased flexibility, particularly in choosing required frequency among wide range of frequencies. This feature has resulted in reduction of the complex control circuitry, which has been progressively replaced by Microcontroller software. The developed methodology is technically observed feasible to generate wide band frequency waveforms precisely without altering hardware configuration increasing the reliability of software based system design. The hardware implementation has been performed and various types of waveforms have been generated, monitored and presented.","PeriodicalId":292408,"journal":{"name":"2019 International Conference on Nascent Technologies in Engineering (ICNTE)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127351558","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}
