An alternate method for computation of transfer function matrix

Abstract

A direct and simple numerical method is presented for calculating the transfer function matrix of a linear time invariant multivariable system (A, B, C). The method is based on the matrix-determinant identity, and it involves operations with an auxiliary vector on the matrices. The method is computationally faster compared to Liverrier and Danilevsky methods. 2010 Appukuttan K. K. and Suma Bhat.
