A modified optimization method for robust partial quadratic eigenvalue assignment using receptances and system matrices

, 2021
In this paper, we focus on the robust partial quadratic eigenvalue assignment problem for vibrating structures by active feedback control. This problem is reformulated as an minimization problem, where the cost function can measure both the sensitivity ...

Eigenvalue assignment enabled control law for multivariable nonlinear systems with mismatched uncertainties

European Journal of Control, 2020
This paper presents an adaptive filtering output feedback control architecture for multivariable nonlinear systems with mismatched uncertainties enabled by an eigenvalue assignment method. A piecewise constant adaptive law updates the adaptive parameters

On the assignment of eigenvalues in LTI systems

Proceedings of the 38th IEEE Conference on Decision and Control (Cat. No.99CH36304), 2003
In this paper we discuss the assignability of natural frequencies of linear time invariant (LTI) systems, given their Hankel singular values. This study is based on the work by Antoulas (1999).

Feedforward controller design by eigenvalue assignment.

The Journal of the Acoustical Society of America, 1991
Active feedforward control algorithms have proved to be successful in the attenuation of stationary disturbances such as single, multiple frequencies, and random inputs. In feedforward control, the mean square value of a measurable response quantity induced by the disturbance input is minimized by coherent ‘‘secondary’’ control inputs.

Simultaneous decoupling and eigenvalue assignment

Proceedings of 1995 American Control Conference - ACC'95, 2005
A new method for simultaneous decoupling and assignment of eigenvalues of a linear square multivariable system is presented. Decoupling and pole-placement conditions are found in a structured way using the Faddeev-algorithm for computing adjoint matrices. The method allows pole-placement of all system poles in contrast to only those poles exceeding the

Minimum norm partial quadratic eigenvalue assignment for vibrating structures using receptance method

Mechanical systems and signal processing, 2019
In this paper, we consider the minimum norm partial quadratic eigenvalue assignment problem (MNPQEAP) for multi-input vibration control systems. Our work is based on the recent paper proposed by Bai et al.

A measure for the decentralized assignability of eigenvalues

Systems & Control Letters, 1988
The results of \textit{R. Eising} [ibid. 4, 263-264 (1984; Zbl 0542.93007)] are generalized to produce a continuous measure of how `close' a mode is to being a decentralized fixed mode [see, \textit{S. H. Wang} and the second author, IEEE Trans. Autom. Control AC-18, 473-478 (1973; Zbl 0273.93047)]. Implications of this measure of controller design are
