this paper is pertained with the problem of admissibility analysis of uncertain discrete-time nonlinear singular systems by adopting the state-space takagi-sugeno fuzzy model with time-delays and norm-bounded parameter uncertainties. lyapunov krasovskii functionals are constructed to obtain delay-dependent stability condition in terms of linear matrix inequalities, which is dependent on the low...

The development of the hardware systems has incurred various types of delays such as processing and transmission delays. Such delay may be due to the effect of tolerances of electronic components which were used while developing the system. Such time delay parameters must be implemented in the transfer function of the system so as to identify the correct cause of dynamic behavior of the system ...

A convenient characterizationi s given for root loci associatedwith open-loop pole-zero dipoles. A particular dipolelocus effect is shownto influence the design of a digital PID controller for an oscillatory pJant;the design is a counterintuitire one in which zeros of the compensator areplaced outside the unit circle in the neighborhood of the plant poles.
