WebThe paper presents the /spl gamma/-/spl delta/ Routh approximation for interval systems. The interval /spl gamma/s and /spl delta/s are evaluated for the higher order interval systems, and then an rth-order approximant is obtained by retaining the first r, interval /spl delta/s, and /spl gamma/s. A numerical example illustrates the procedure. WebAbstract: A new method of approximating the transfer function of a high-order linear system by one of lower order is proposed. Called the "Routh approximation method" because it is based on an expansion that uses the Routh table of the original transfer function, the method has a number of useful properties: if the original transfer function is stable, then …
