Abstract: A new technique in the design of controllers for linear dynamic systems with periodically varying coefficients is presented. The idea is to utilize the well-known Liapunov-Floquet (L-F) transformation ...

Abstract: In this work, the basic problem of order reduction of nonlinear systems subjected to an external periodic excitation is considered. This problem deserves special attention because modes that ...

Abstract: For most complex dynamic systems, it is not always possible to measure all system states by a direct measurement technique. Thus for dynamic characterization and controller design purposes, it ...

Abstract: The problem of designing controllers for nonlinear time periodic systems via feedback linearization is addressed. The idea is to find proper coordinate transformations and state feedback under ...

Abstract: In this study, a passive control system has been proposed to protect structures from earthquake damages. In particular, the influence of an absorber on the dynamics of base‐isolated structures has been investigated in ...

Abstract: Panel flutter suppression by exact state transformations and feedback control using piezoelectric actuation is presented. A nonlinear control system is designed for a simply supported rectangular ...

Abstract: In this study a possible application of time-dependent canonical perturbation theory to a fast nonlinear time-periodic Hamiltonian with strong internal excitation is considered. It is shown that ...

Abstract: The paper deals with an approximate analytical technique for solving the boundary-value problems governed by second-order differential equations with variable coefficients. The variable coefficient ...

Abstract: In this paper, a new analysis technique in the study of dynamical systems with periodically varying parameters is presented. The method is based on the fact that all linear periodic systems ...
