英文摘要：
Chaotic signals from Logistic map in different amplitudes and intensity are used to sup press spiral of active media successfully. Fitzhugh-Nagumo （FHN） and Panfilov equations are studied. The reason why chaotic behavior overcomes the behaviors of spiral is considered when chaotic signal is input into the system. The numerical simulation results prove that the anti-control scheme is effective. The interesting point is that system becomes homogeneous quickly and keeps invariable even when the chaotic driving signal is terminated in about 50 time units later.Our results show that chaotic signal driving is different from noise-induced spiral as the chaotic signal differs from noise greatly.
