| 英文摘要 |
| In this paper, the control purpose of degenerating multi-scroll attractors and suppressing chaos is realized
through linear augmentation control based on three chaotic systems, including a 3D Lorenz two-wing system, a 3D fourwing
system and a 4D four-wing system. By increasing the coupling strength between the two systems, partial equilibrium
points of the multi-scroll chaotic system are moved and gradually eliminated. The system dynamical behaviors are investigated
by the curves of equilibrium points, bifurcation diagram, Lyapunov exponents and phase trajectory diagrams. In
order to verify the effectiveness and circuit realizability of linear augmentation control, based on the 3D four-wing system,
a chaotic circuit is designed. The Multism simulation and hardware experimental results are in agreement with that of the
MATLAB. |
