Design of linear quadratic regulators with assigned eigenstructure

A recursive design procedure is presented which assigns the closed-loop eigenstructure in linear quadratic regulators. At each stage, the required solution for the steady-state Riccati matrix which shifts a pole or pole pair to specified values is obtained. For pole pair placement, a free parameter in the solution permits selection of closed-loop eigenvectors. The interactive design procedure is summarized and illustrated by an example
