Design andExperimental Evaluation ofComposite OutputFeedback Control forSmartStructures

Thispaperproposes acomposite output feedbackstructures canbeseenin(2,6,7).Theproblem withthese controller whichconsists ofperiodic output feedback and control techniques isthat thestate feedback controller needs fastoutputsampling feedback controller. Eachofthe either theavailability ofthestate vector oranestimator. The controllers isdesigned tosuppress theparticular vibration output feedback requires onlythemeasurement ofsystem mode.Theproposed controller isapplied tocontrol the output butthere isnoguarantee ofstability ofclosed loop first twovibration modesofa piezoelectric actuatedsystem. Thestatic output feedback problem isoneofthemost cantilever beam.Theperformance ofthecontroller is investigated problems incontrol theory andapplications. One shownbysimulation andexperimental results. A digital reasonwhystatic output feedback hasreceived somuch control system thatconsists ofsimulink modeling softwareattention isthat itrepresents simplest closed loopcontrol that and dSPACE 1104 controller boardis usedfor canberealized inpractice (11). Theperiodic output feedback identification andcontrol. control andfast output sampling feedback control shownby WernerandFutura (12,13)hasthefeatures ofstatic output
