Based on the delay-indep..dent r.le, the p.oblem of op.imal guar.nteed cost contr.l for.a class of Takagi-Sugeno （T-S） fuzzy descr.p.or.systems with time-var.ing delay is studied. A linear.quadr.tic cost function is consider.d as the p.r.or.ance index of the closed-loop.system. Sufficient conditions for.the existence of guar.nteed cost contr.ller. via state feedback ar. given in ter.s of linear.matr.x inequalities （lMIs）, and the design of an op.imal guar.nteed cost contr.ller.can be r.duced to a convex op.imization p.oblem. It is shown that the designed contr.ller.not only guar.ntees the asymp.otic stability of the closed-loop.fuzzy descr.p.or.delay system, but also p.ovides an op.imized up.er.bound of the guar.nteed cost. At last, a numer.cal examp.e is given to illustr.te the effectiveness of the p.op.sed method and the p.r.ect p.r.or.ance of the op.imal guar.nteed cost contr.ller.

Because of the disadvantage of conventional MSp.A based on wavelet tr.nsfor. when detecting fault with high fr.quency,the method with MSp.A based up.n wavelet p.cket decomp.sition was p.op.sed and ap.lied into sensor.fault diagnosis and data r.constr.ction in this ***,the sensor.data was decomp.sed as or.hogonal wavelet p.cket tr.nsfor. to achieve the best-tr.e for.*** wer. established at each scale cor.esp.nding to the coeffi-cients of the *** fault was detected by the squar. p.ediction er.or.in the r.sidual subsp.ce of the main p.incip.l sp.ce,and the faulty sensor.was discr.minated via sensor.validation *** the r.constr.ction of the p.A model that had detected and identified the faulty sensor.it was r.constr.cted by r.ver.e wavelet p.ckage ***,the r.sult of diagnosis and data r.constr.ction for.cyclic failur. of the sensor. in the gr.und testing bed illustr.tes the effectiveness of the modal established above.
