摘要

Maintaining oscillation is essential for practical applications in various natural and artificial systems, thus, restoring rhythmic oscillation from amplitude death (AD) always plays an important role in the real world. In this paper recovery of oscillation has been investigated in Stuart-Landau oscillators with conjugate coupling topologies. Two asymmetry coupling strategies have been firstly employed and utilized in the coupled Stuart-Landau oscillators by introducing asymmetry factors in the coupling topology. It has been found that, via adjusting the asymmetry factors, the AD regions shrink evidently in the parameter plane, recovering the oscillation rhythmicity efficiently in the coupled identical oscillators or nonidentical oscillators. Therefore it provides a candidate to eliminate the AD state and evoke rhythmic oscillation in coupled Stuart-Landau oscillators.
