An efficient computational algorithm for pole assignment of linear n-th order m-input systems is proposed. The algorithm requires a small multiple of n3 operations and approximately n2 + (n + m)2â€¦ (More)

The perturbation techniques and numerically stable computational methods are discussed for the basic problems of the analysis and design of linear control systems: stability analysis,â€¦ (More)

In this paper we give effective estimates for the distance of a stable matrix to the set of unstable matrices for both the continuous- and discrete-time cases. The first estimate is based onâ€¦ (More)

This paper presents a complete perturbation analysis of the continuous and discrete matrix algebraic equations in the theory of linear-quadratic optimization. In particular the conditioning of theâ€¦ (More)

In biophysical models and in acute experiments on animals, the air was administered in measured volumes into the artificial blood flow and into the common carotid artery in dogs. When air bubbles getâ€¦ (More)
