钉扎信号控制耦合映像格子系统的电路仿真

Electronic circuit simulation on pinning control of spatiotemporal chaos in a coupled map lattice

设计耦合映像格子电路系统, 用电路实现了钉扎非线性反馈信号控制时空系统, 通过在Pspice平台上的仿真, 得到将系统控制到预期目标态(如不动点) 的结果, 与数值计算及理论分析一致,实验验证了钉扎方法控制时空混沌系统的有效性.

An electronic circuit of coupled map lattices and a scheme for pinning a nonlinear feedback control spatiotemporal chaotic system were implemented. Using the Pspice circuit simulator, we found that the system can be controlled to the desired state which is a fixed point. The experimental results are in good agreement with those obtained by numerical simulation and theoretical analysis. Our results confirm that spatiotemporal chaotic system can be controlled by the pinning control.
