On the determination of the zeros of a SISO system
K.S. Yeung, Yizhen Huang · IEEE Transactions on Automatic Control · 1989
A formula to find the zeros of a SISO (single-input-single-output) system, as eigenvalues of a certain matrix M, from state-space description is presented. Since the numerical computation of eigenvalues can be very accurate, the formula provides a way to determine accurately the zeros of a high-order SISO system.>
