bounded error

By the introduction of a compensation term in the design of the sliding mode observer that counteracts the effect of system deviations to the velocity reconstruction, the exponential observation error is converged to a bounded region.

在滑模观测器设计中引入补偿项，动态抵消系统偏差对速度重构的影响，确保观测误差指数收敛到有界域。

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.

证明了，滤波器被充分激励时，如果噪声干扰足够小，且采用低自适应速率，滤波器的参数和输出误差是渐近有界的。

The proposed approach updates the estimates selectively depending on whether the observed data contain sufficient new information and can ensure that the worst-case estimation error is bounded and non-increasing.

该算法通过对测量数据是否包含足够的新息来决定估计更新的选择，同时能够确保所得到的最坏情况估计误差是有界而且非增的。

In this paper, a direct adaptive control algorithm is presented for the controlled autoregressive integrated moving-average ( CARIMA) model with bounded disturbances and the proof of its global stability is carried out The algorithm can deal with nonminimum-phase systems and guarantee a steady-state zero-error output.

本文对存在有界扰动的CARIMA模型提出一种自适应控制算法，并进行了稳定性分析.该控制算法可用于非最小相位系统的控制，并能保证输出无稳态误差。

To insure the system error is uniformly ultimately bounded ( UUB), the update laws of the coarse/ fine subnet are designed respectively.

为了确保系统误差一致最终有界收敛，分别设计了粗/细子网的权值更新律。
