Abstract: This technical note presents a method of checking the number of complex eigenvalues in some interested regions or the multiplicity of some complex eigenvalues for nonproportionally damped system. A Schur–Cohn matrix is ...

Abstract: This paper proposes an implementation of modal control for seismically excited structures using magnetorheological (MR) dampers. Many control algorithms such as clipped-optimal control, decentralized bang-bang control, and ...

Abstract: This paper experimentally investigates the feasibility of an adaptive passive control system, which consists of a magnetorheological (MR) fluid damper and an electromagnetic induction (EMI) part, for suppressing vibration ...

Abstract: Natural frequencies and mode shapes of structures are determined from eigenvalue analysis. This paper proposes a subspace iteration method with an accelerated Lanczos starting subspace for the efficient eigenvalue analysis ...
