This paper aims to study the stochastic period-doubling bifurcation of the three-dimensional Rssler system with an arch-like bounded random parameter. First, we transform the stochastic Rssler system into its equivalent deterministic one in the sense of minimal residual error by the Chebyshev polynomial approximation method. Then, we explore the dynamical behaviour of the stochastic Rssler system through its equivalent deterministic system by numerical simulations. The numerical results show that some stochastic period-doubling bifurcation, akin to the conventional one in the deterministic case, may also appear in the stochastic Rssler system. In addition, we also examine the influence of the random parameter intensity on bifurcation phenomena in the stochastic Rssler system. 相似文献

This paper aims to study the stochastic period-doubling
bifurcation of the three-dimensional R?ssler system with an
arch-like bounded random parameter. First, we transform the
stochastic R?ssler system into its equivalent deterministic one
in the sense of minimal residual error by the Chebyshev polynomial
approximation method. Then, we explore the dynamical behaviour of
the stochastic R?ssler system through its equivalent
deterministic system by numerical simulations. The numerical results
show that some stochastic period-doubling bifurcation, akin to the
conventional one in the deterministic case, may also appear in the
stochastic R?ssler system. In addition, we also examine the
influence of the random parameter intensity on bifurcation
phenomena in the stochastic R?ssler system. 相似文献

提出了基于人工智能负载估计系统的磁浮列车悬浮系统主动控制方法。给出单点悬浮数学模型,并基于劳斯-赫尔维兹判据证明该模型开环不稳定;考虑负载特征和实时悬浮变化,利用多层人工神经网络对悬浮系统控制量的输出进行主动控制;采用非支配排序遗传算法(NSGA)对系统参数进行优化。结果表明:所提出的控制方法具有较好的鲁棒性,在较大负载扰动时仍然能够保持相对较小的误差。 相似文献
