DTIC ADA361654: Robust Eigenstructure Assignment Using Positive Definite Output Feedback Control. by. Defense Technical Information Center.

The freedom provided by output-feedback eigenstructure assignment is used to optimize some performance functions which are used to measure the sensitivity of the closed-loop matrix and the robustness of the closed-loop.

The freedom provided by output-feedback eigenstructure assignment is used to optimize some performance functions which are used to measure the sensitivity of the closed-loop matrix and the robustness of the closed-loop system.

This paper investigates a new approach for the design of robust output feedback controllers with respect to minimizing the condition number of the closed-loop eigenvector matrix. Relying on a recently proposed procedure for parametric eigenstructure assignment, we exploit the degrees of freedom in the design to achieve our result.

The state feedback pole assignment problem in control system design is essentially an inverse eigenvalue problem, which requires the determination of a matrix having given eigenvalues (cf. Fletcher .

The Output Feedback Eigenstructure Assignment Theorem. In the eigenstructure assignment approach, the residual is generated using an observer with the following structure: (50). Let (A, B) be controllable and (A, C) be observable. Assume that rank(B) m and rank(C) r. Then max(m, r) eigenvalues and max(m, r) eigenvectors with min(m, r) entries in each eigenvector can be assigned by the output feedback law (1. The unknown input observer is a robust observer in which FDI residuals become insensitive to uncertainty. For FDI purposes, it is not necessary to ensure that the state estimâtes have this insensitivity. x^t Acx^t+But+Kyty^t Cx^t.

This article presents a new partial eigenstructure assignment method. A state feedback control law is used to construct the stabilizing controller. Keywords: Fuzzy systems, Constrained control, Positive invariance. by benzaouia abdellah benzaouia abdellah. This technique keeps the open-loop stable eigenvalues and the corresponding eigenspace unchanged. This article presents a new partial eigenstructure assignment method. A numerical example is presented to illustrate the technique.

This is a AIR FORCE INST OF TECH WRIGHT-PATTERSONAFB OH SCHOOL OF ENGINEERING report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A456163. The abstract provided by the Pentagon follows: This research investigates a method of eigenstructure assignment for the classes of controllers known as positive definite output feedback control. The research began with a closed loop system with output feedback control that utilizes a collocated actuator-sensor pair. It is shown that this system is robust because it is globally stable for positive definite feedback. Analytical analysis is then completed to determine gains that minimize a cost function that is the error between the desired and achievable (assuming positive definite output feedback) eigenstructure. Examples are given at the end of the thesis to validate the computer code and theory results.
