Evolutionary Approach for Model Order Reduction

Publication date: Available online 27 April 2016 Source:Perspectives in Science Author(s): Shilpi Lavania, Deepak Nagaria The phenomenon of compact model has become an extensive area of research. This paper presents a mixed approach for model order reduction of a single input and single output system (SISO). The technique is based on Padé approximation which gives equal emphasis to time moments and markov parameters and a nature based particle swarm optimization approach. In this mixed method numerator is derived using particle swarm optimization and denominator is derived using Padé approximation. The worthiness and effectiveness of the method is investigated in terms of integral square error (ISE). Numerical example is verified and compared with various existing techniques on the basis of integral square error (ISE) to prove the superiority of the proposed method. The proposed method guaranties the stability of the reduced order system.
