Dynamic analysis of the non-linear behavior of an ocean buoy for energy harvesting
(2021-01-01)
We investigated the nonlinear dynamic behavior of the system for energy harvesting using ocean wave motion. The system consists of a linear electromagnetic system coupled to a float to move with ocean waves. We define the ...
Incorporation of hard excitation limits into power system normal form analysis
(2009)
In this paper a theoretical framework for the incorporation of the effect of excitation limits on normal form analysis is presented. The limiter action is approximated by a smooth nonlinear type atan function which is ...

On the dynamics behavior and a control design to a nonlinear 2-DOF vibrating gyroscopic-MEMS model
(2011-12-01)
In this paper, we deal with the nonlinear dynamics, the transfer of energy and control of the vibrations of a Micro Electro-mechanical System (MEMS) gyroscope. The MEMS are micro-transducers whose operation is based on ...
On chaotic dynamics of a double pendulum arm excited by a nonlinear shaker based rlc circuit
(2013-01-01)
The chaotic dynamics of a double pendulum arm coupled to a nonlinear shaker based RLC circuit through a magnetic field is studied numerically. The nonlinear term, in the circuit, is introduced by considering that the voltage ...
