Model-Order Reduction Usage of Stability Equation Method Designed for Discrete-Time Systems

This paper presents, a higher-order transfer function of DTS, reduced with stability equation method (SEM). For the reduction of DTS transfer function, indirect method is used. The ROM (Reduced Order Model) is founded on the pole-zero designs. In this work, using the SEM shows the graphical evaluation of step responses of ROM and other literature methods. The comparison displays improved results of proposed ROM than further approaches obtainable in literature. The analysis stays founded upon settling time, peak time, peak and rise time information of real model and ROM.
