Available in PDF, EPUB and Kindle. Book excerpt: A software Voter/Monitor (V/M) system is designed and implemented. The V/M is an informational processing device which is to be used in a digital flight control system (DFCS). A DFCS is currently being developed to replace existing analogue flight control systems in selective military aircrafts. The V/M receives data over four separate input channels, and it performs a processing routine which (a) allows it to continually select one of the input channel data for routing over its single output channel; and (b) allows it to maintain a history of each input channel data for routing over its single output channel; and (b) allows it to maintain a history of each input channel performance and declare as defective any input channel from which it consistently receives 'bad' data. The V/M is implemented using the National Semiconductor IMP-16L Microcomputer. The V/M processing scheme uses input-input comparison monitoring. Software coding and hardware circuitry are designed. Additionally, a software test program is constructed. The V/M system testing is limited. The correct performance of the V/M system is illustrated under a static testing environment.
Download or read book The Evaluation of a Digital Hardware Voter monitor in an Aircraft Control System written by Harry W. Schreadley and published by . This book was released on 1977 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes an evaluation and presents the test results of a Digital Hardware Voter/Monitor used as an input signal selector and fault detector when used in conjunction with an electro-hydraulic control system. The DHVM operated as intended by design although asynchronous operation caused the failure detection to be frequency dependent. A digital filter could be incorporated to reduce the frequency dependency of the failure detection circuitry. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: In the future digital processors will be used to compute control surface deflections based upon pilot inputs, current surface position and other variables. The purpose of this investigation was to generate an algorithm to choose the best output signal from among four asynchronous inputs. The problem was divided into two tasks: comparison monitoring and signal selection. The use of an IMP-16C microprocessor to implement the algorithm is discussed and the design of an interface which will allow communications between the flight control processors and the digital voter/monitor is presented.

This book was released on 2013-11-21 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for lnformation and Numerica/ Data Analysis and Synthesis (C/NDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficia! to the academic and general scientific and technical community. After fi ve years of this joint undertaking we had concluded that it was in the interest of ali concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and App/ied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. Ali back issues can also be ordered from Plenum. We have reported in Volume 21 (thesis year 1976) a total of 10,586 theses titles from 25 Canadian and 219 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work.
