Eigenstructure Assignment of LQR via Homotopy Method

Optimised Eigenstructure Assignment by Ant System And LQR Approaches

Recently, it has been verified that applications of metaheuristics for finding optimal or suboptimal solutions for NP-hard optimisation problems is one of the most promising research fields. Using the ant system metaheuristic, this paper proposes a new design method for state feedback control law which simultaneously achieves the linear quadratic stabilisation and an eigenstructure assignment c...

Reconfiguring Second-order Dynamic Systems via P-D Feedback Eigenstructure Assignment: A Parametric Method

Abstract: The design of reconfiguring a class of second-order dynamic systems via proportional plus derivative (P-D) feedback is considered. The aim is to resynthesize a P-D feedback controller such that the eigenvalues of the reconfigured closed-loop system can completely recover those of the original close-loop system, and make the corresponding eigenvectors of the former as close to those of...

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...
