Free Vibration Analysis of a Nonlinear Beam Using Homotopy and Modified Lindstedt-Poincare Methods
In this paper, homotopy perturbation and modified Lindstedt-Poincare methods are employed for nonlinear free vibrational analysis of simply supported and double-clamped beams subjected to axial loads. Mid-plane stretching effect has also been accounted in the model. Galerkin's decomposition technique is implemented to convert the dimensionless equation of the motion to nonlinear ordinary differ...
متن کاملNumerical Solution of the Controlled Harmonic Oscillator by Homotopy Perturbation Method
The controlled harmonic oscillator with retarded damping, is an important class of optimal control problems which has an important role in oscillating phenomena in nonlinear engineering systems. In this paper, to solve this problem, we presented an analytical method. This approach is based on the homotopy perturbation method. The solution procedure becomes easier, simpler and mor...
متن کاملA Double Homotopy Approach for Decentralized ∞ Control of Civil Structures
This paper presents a decentralized ∞ controller design for the vibration control of civil structures. The formulation through double homotopy is proposed in discrete time domain and considers feedback time delay. It is well known that through bounded real lemma, ∞ controller design can be transformed to an optimization problem with bilinear matrix inequality (BMI) constraints. To obtain a de...
متن کاملVibration Analysis of a Nonlinear Beam Under Axial Force by Homotopy Analysis Method
In this paper, Homotopy Analysis Method is used to analyze free non-linear vibrations of a beam simply supported by pinned ends under axial force. Mid-plane stretching is also considered for dynamic equation extracted for the beam. Galerkin decomposition technique is used to transform a partial dimensionless nonlinear differential equation of dynamic motion into an ordinary nonlinear differenti...
متن کاملDecentralised proportional-plus-integral design method for interconnected power systems - Generation, Transmission and Distribution [see also IEE Proceedings-Generation, Transmission and D
A simple and computationally efficient decentralised control design method is introduced for load-frequency control (LFC) in interconnected power systems. The method is based on the use of a reduced-order observer and a proportional-plus-integral controller in each area of the power system, and ensures zero static change in area-frequency and tie-line power. Some of the features of the decentra...
