DOI: 10.1016/j.jsv.2018.02.036
Abstract: Abstract Eigenvalues and eigenvectors play a fundamental role in determining the dynamic behavior of a vibrating system. Thus, an important goal in vibration control is to modify the eigenstructure to match the design specifications. Feedback… read more here.

DOI: 10.1016/j.ymssp.2016.08.046
Abstract: Abstract The assignment of the eigenstructure (i.e. eigenvalues and eigenvectors) in vibrating systems is an effective way to improve their dynamic performances. System controllability ensures that the poles of the controlled system are exactly assigned… read more here.

DOI: 10.1080/00207721.2025.2504051
Abstract: The problem of eigenstructure assignment in linear systems via state-derivative feedback is considered. A new derivative feedback design framework named complementary system framework is proposed. By using this framework, notions of complementary controllability and complementary… read more here.
