small perturbation

Based on the homeomorphous transformation for the model, it can be concluded that if the chaotic attractor for the diagonal is stable for the transverse small perturbation in neighborhood, it should be globally stable in the whole feasible set.

通过对模型的同胚变换可得到：如果对角线上的混沌吸引子在垂直于对角线方向上局部稳定，那么它在可行集的范围内也全局稳定。

It is proved that when the filter is sufficiently excited the parameter and output error in the filter are asymptotically bounded if nowise perturbation is sufficiently small and the lower rate of convergence is used.
