Anderson Corollary Based on New Approximation Method for Continuous Interval Systems
In this research, a new technique is developed for reducing the order of high-order continuous
interval systems. The model denominator is derived using Anderson corollary and Routh table. Numerator
is derived by matching the formulated Markov parameters (MPs) and time moments (TMs). Distinctive
features of the proposed approach are: (i) New and simpler expressions for MPs and TMs; (ii) Retaining
not only TMs but also MPs while deriving the model; (iii) Minimizing computational complexity while
preserving the essential characteristics of system; (iv) Ensuring to produce a stable model for stable system;
(v) No need to invert the system transfer function denominator while obtaining the TMs and MPs; and (vi)
No need to solve a set of complex interval equations while deriving the model. Two single-input-singleoutput test cases are considered to illustrate the proposed technique. Comparative analysis is also presented
based on the results obtained. The simplicity and effectiveness of the proposed technique are established
from the simulation outcomes achieved
