Design of a state feedback controller to achieve minimum eigenvalue differential sensitivity

Record type: Article

This paper introduces a new design method using eigenstructure assignment. The differential sensitivity of the eigenvalues of the system is minimized. The method involves minimizing the least-squared error between the achievable and the desired eigenspace to achieve mode decoupling. A global measure of eigenvalue sensitivity for all desired eigenvalues that make the closed-loop system insensitive to perturbations or parameter variations is included in the method. The technique requires the use of a gradient-based algorithm. The method is illustrated by an example, which is intended to show a more flexible approach to eigenstructure assignment.
