The reference is outfit for both sub 1V and above 1V applications. The circuit design consists of basic beta multiplier configuration and offers a strategy of making the current sourcing circuit and reference generating circuit as independent units. A simulation model of the circuit was built in T-Spice, 0.35μm CMOS process. Simulation results show high amount of temperature insensitivity for a large range of thermal conditions. The reference voltage variation is about 1.65mV/°C to 1.67mV/°C over wide temperature range of -40 to 140°C; has an impressive static supply dependency of 125μV/V for a reference of 280mV. The circuit can also be operated at very low supply voltage (0.5v).","PeriodicalId":187091,"journal":{"name":"2012 Proceedings of IEEE Southeastcon","volume":"500 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132313275","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 adds to fault tolerant control in the area of faulty sensors. This is done by taking advantage of redundancy in a linear system to create a set of reduced order observers. Each reduced order observer is designed to isolate faults from a single sensor. This method of fault isolation produces sensor fault tolerance. Certain classifications of sensor faults are completely removed from the system by this method. The work further continues to show how to measure the removed fault. The bank of reduced order observers produce fault information, in addition to reconstructing fault-free sensor estimates.","PeriodicalId":187091,"journal":{"name":"2012 Proceedings of IEEE Southeastcon","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123709359","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}

UAVs are finding applications in various areas ranging from military applications to traffic surveillance. This paper is a survey for a certain kind of UAV called quadrotor or quadcopter. Researchers are frequently choosing quadrotors for their research because a quadrotor can accurately and efficiently perform tasks that would be of high risk for a human pilot to perform. This paper encompasses the dynamic models of a quadrotor and the different model-dependent and model-independent control techniques and their comparison. Recently, focus has shifted to designing autonomous quadrotors. A summary of the various localization and navigation techniques has been given.

As part of the EcoCar Challenge, ERAU has been developing the Intelligent Driver Efficiency Assistant (IDEA), an advanced predictive supplementary control system for the university's EcoCAR 2 competition vehicle. The goal of the IDEA system is to minimize the emissions and energy consumption of ERAU's hybrid-electric vehicle through the application of artificially intelligent, and adaptive and predictive control system theory. These predictions allow IDEA to place its control system in the best possible mode of operation to minimize overall vehicle emissions and energy consumption.

The course is for senior students majoring in electrical or mechanical engineering technology. Topics discussed as part of the course include PID controllers, fuzzy logic control principles, robot mechanics, sensors for mobile robots, FPGA embedded systems implementation, and robot path planning techniques. The main goal of this course is to apply the above topics to the design and implementation of an autonomous navigation robot. Working in collaborative groups, by the end of the semester students were able to have a complete functional autonomous mobile robot capable of performing search and rescue tasks. To achieve the autonomous navigation, students focused in the implementation of two different types of controllers, a PID control and a fuzzy logic based control; both controllers were implemented in an FPGA card. Students also designed a rubric to assess the performance of the two different controllers to evaluate and compare them.","PeriodicalId":187091,"journal":{"name":"2012 Proceedings of IEEE Southeastcon","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123474963","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}
