Interval Analysis of the Eigenvalues of Closed-Loop Control Systems with Uncertain Parameters
Actuators, 2020 Uncertainty caused by a parameter measurement error or a model error causes difficulties for the implementation of the control method. Experts can divide the uncertain system into a definite part and an uncertain part and solve each part using various ...

Spectral Properties and Finite Pole Assignment of Linear Neutral Systems in Banach Spaces
Abstract and Applied Analysis, 2010 We will consider a pole assignment problem for a class of linear neutral functional differential equations in Banach spaces. We will think of the neutral system studied as that of involving no time delays and reduce the study of adjoint semigroups and ...

On the regulator problem for linear systems over rings and algebras
Open Mathematics, 2021 The regulator problem is solvable for a linear dynamical system Σ\Sigma if and only if Σ\Sigma is both pole assignable and state estimable. In this case, Σ\Sigma is a canonical system (i.e., reachable and observable).

Receptance-Based Partial Pole Assignment for Asymmetric Systems Using State-Feedback
Shock and Vibration, 2012 Many structures or machines interact with some internal nonconservative forces and present asymmetric systems in which the stiffness and damping matrices are asymmetric. Examples include friction-induced vibration and aeroelastic flutter.

Robust eigenstructure assignment under regional pole constraints [PDF]
, 1996 This paper provides a computational procedure for a type of robust regional pole assignment problem. It allows the closed-loop poles to be settled at certain perturbation insensitive locations within some prespecified regions in the complex plane.

Robust and Arbitrary Pole Placement using Static Output Feedback [PDF]
E3S Web of ConferencesThis paper presents the output feedback pole assignment methods that attempt to achieve a robust solution where the arbitrary choose of the poles to be assigned are as insensitive as possible to perturbations in the closed loop system.
