Abstract:
We propose a method for effective control of patter on dissipative system by use of little perturbation analysis, and apply this nonuniform feed back method to control the polarization wave of heart represented by FHN equation. In the numerical experiment, we successfully alter the propagating direction of planar waves and drift the spiral waves to boundary without resonant repulsion. The effective control of the excited system will be used to study the mechanism of defibrillation and that is our interesting work.
