Abstract
In this paper, from the viewpoint of eigenvalues and eigenvectors assignment, some considerations about improvement of transient characteristics of output feedback control systems are described.
For a controllable and observable multiinput system with n states, m inputs and l outputs, if n≤m+l-1, then almost arbitrary sets of closed-loop eigenvalues are assignable by using output feedback. Then, in general, some degrees of freedom remain in eigenvector assignment after the eigenvalues have been assigned. Therefore, transient characteristics may be improved by making use of these degrees of freedom in eigenvector assignment.
In this paper, this improvement method is described and its effectiveness is shown by the numerical examples.
