Algorithm place uses the algorithm of [1] which, for multi-input systems, optimizes the
choice of eigenvectors for a robust solution. We recommend
place rather than
acker even for single-input systems.
In high-order problems, some choices of pole locations result in very large
gains. The sensitivity problems attached with large gains suggest caution in
theuseof poleplacement techniques.See [2]for resultsfrom numericaltesting.
