Abstract :
This paper proposes an improved technique for order reduction of discrete-time interval systems based on modified γ-δ Routh Approximation method. The denominator of reduced order model is evaluated using modified γ-table which is constructed through incorporation of Dolgin & Zehab´s concept [14]. A numerical example is included to illustrate the proposed algorithm along with the comparison with existing techniques.
