Phase Dynamics for Nonlinear Dissipative Waves under External and Feedback Control
نویسنده
چکیده
We study dynamics of traveling waves under spatiotemporal forcing in non-equilibrium systems. Based on the model equations of nonlinear dissipative systems where traveling waves are formed in a self-organized manner, we apply external and feedback forcing to the traveling waves. Entrainment and modulation of the traveling waves are investigated numerically and analytically in one dimension. In the present paper, we focus our attention on the trapped oscillations of the waves under the external forcing and the propagation reversal in the feedback forcing. A phase dynamic approach is developed to formulate these interesting and unexpected dynamics.

External forcing and feedback control of nonlinear dissipative waves.
The dynamics of traveling waves in a nonlinear dissipative system are studied analytically and numerically. Spatiotemporal forcing and feedback forcing are applied to the traveling waves in a phase-separated system undergoing chemical reactions. The stability of the traveling waves and interesting, unexpected behavior, including the reversal of the propagation direction are analyzed in one dime...

In this paper, a novel approach for finite-time stabilization of uncertain affine systems is proposed. In the proposed approach, a fast terminal sliding mode (FTSM) controller is designed, based on the input-output feedback linearization of the nonlinear system with considering its internal dynamics. One of the main advantages of the proposed approach is that only the outputs and external state...
