Increasing eigenstructure assignment design degree of freedom using lifting

Using Post-eigenstructure Assignment Design Freedom for the Imposition of Controller Structure

Recent algorithm developments in the field of output-feedback eigenstructure assignment make use of the available design freedom in a multi-stage assignment process. Depending on the number of degrees of freedom available and the manner in which they are distributed between the stages, it is possible that not all will be used. This paper develops an algorithm by which these excess degrees of fr...

Eigenstructure Assignment for Control

Robust Eigenstructure Assignment: New Approach

This paper considers the problem of robust eigenstructure assignment, which involves finding a feedback gain matrix that makes the closed-loop system insensitive to perturbations or parameter variations. The main contribution of the paper is to derive a new robustness measure using the matrix perturbation theory. The new measure is used to formulate a new method for robust control of the system...

Eigenstructure Assignment in Reconfigurable Control Systems Eigenstructure Assignment in Reconfigurable Control Systems

An optimization approach to control reconnguration, based on eigenstructure assignment , for control systems with output feedback is presented. The emphasis is on the recovery of the nominal closed-loop performance, which is determined by the closed-loop eigenvalues and eigenvectors. The proposed scheme preserves the max(r; q) most dominant eigenvalues of the nominal closed-loop system and dete...
