Abstract :
The authors present a numerically stable algorithm for assigning a prescribed set of zeros to a linear system described by a state-space model (A, B, C, D). The method is based on the generalized Schur form of the system matrix, and the implicitly shifted QR algorithm. The approach imposes no restrictions on the state-space model, and does not require computation of the zeros of the original system. Numerical properties of the algorithm are discussed and examples are given to illustrate its performance.<>
