Model Order Diminution of Discrete Interval Systems Using Kharitonov Polynomials

In this research proposal, diminution of higher order (HO) discrete interval system (DIS) is accomplished by utilizing Kharitonov polynomials. The DIS firstly, transformed into continuous (CIS). Markov-parameters (MPs) and time-moments (TMs) are exploited for determination approximated models. ascertainment model (MOD) DISs done Routh-Padé approximation. Routh table utilized to obtain the denominator model. unknown numerator coefficients desired determined matching MPs TMs This whole procedure MOD elucidated with help one test illustration in which third reduced first as well second To prove applicability proposed method, impulse, step Bode responses plotted both For relative comparison, time-domain specifications tabulated upper lower limits. Further, performance indices specified dissimilarities between obtained results depict effectiveness efficacy method.
