Certain investigations on fault tolerant control techniques for linear systems

Abstract

This research work deals with fault diagnosis and fault tolerant newlinecontrol in linear systems Fault diagnostic procedures are basically techniques newlinethat detect the presence of fault in a system Fault tolerant control aims at newlinemaking the system continue to work in spite of the occurrence of fault but newlinewith a slightly degraded performance Faults that occur even in a single newlinecomponentsubsystem of a large system may cumulatively lead to overall newlineperformance deterioration and improper system behavior The major newlinechallenge in the research work undertaken is to identify and bridge the gap newlinebetween the actual faults and parameter variation of the componentssystems newlinewithin their tolerances In this open area of research there are still unsolved newlineand unraveled problems Few such problems have been identified and newlinetechniques have been proposed in this research work As control systems newlineoccupy every walks of life failure of any componentsystem affects the newlinereliability and sometimes results in catastrophic damage Serious challenges newlineare encountered in detecting the fault occurrence owing to the complex newlinesystem behavior influence of environmental conditions etc newline
