Abstract :A multi-objective optimization based graphical procedure to derive a reduced order insert ignore into journalissuearticles values(rth-order); approximant for given insert ignore into journalissuearticles values(stable); SISO linear continuous-time system is presented. In this method, stability and the first r time moments/Markov parameters are preserved as well as the errors between last r time moments/Markov parameters of the system and those of the model are minimized. The method is useful as it alleviates the problems of deciding the values of number of error functions to be minimized and values of weights on the errors in arriving at good approximantsKeywords : Model reduction, Padé approximation, Routh criterion, VEGA
