在非线性系统中未知参数的边界值未知的情况下，提出了切换自适应控制设计方法。

Both analysis and practical computing show that this filter can get a much lower variance bound than a priori one can.

理论分析和实际计算结果表明，本算法能达到比验前滤波小得多的滤波误差的方差上界。

Using the property of the bilinear and trilinear form, a priori bound for solutions of a weak formulation is given.

利用双线性函数和三线性函数的性质，论述了各子问题的有界性、强制性以及解的先验估计。

Of course,one may choose to use an a priori upper bound on the number of nodes in the system;for example,we could postulate at most one Chord server per IPv4 address.

当然， 你也许选择使用一个演绎最高界面在结的数量在system；for 例子，我们能假设至多一台弦服务器每IPv4 地址。

An adaptive algorithm is also incorporated to remove the requirement for a priori knowledge about the upper bound of the derivative of observed signal.

而其中适应性控制法则是用来消除"需要知道信号其导数上界"的这一项前题。

By exploiting the important properties of robot dynamics, the second strategy removes the requirement of a priori bound on parametrer uncertainty and weakens the restriction on external disturbance. The only requirement is to know an upper bound of the norm of inertia matrix, which is not necessary to be the smallest.

第二种算法利用机器人固有的结构特性，减弱了目前已有文献对未建模扰动的限制，它不要求预先知道机器人结构参数的不确定范围，仅要求已知实际惯量矩阵范数的一个上界。

Because a posteriori filter can generally get lower variance bound than a priori one, a posteriori filtering method is also given, which is unbiased to the nominal system of the interval one under consideration.

由于验后滤波算法精度比验前滤波精度高，研究了区间系统鲁棒验后滤波算法，相对区间系统的标称系统来说本文给出的鲁棒验后滤波是无偏的。

The authors investigated the singular limits of stiff relaxation and dominant diffusion for general 2×2nonlinear systems of balance laws, that is,τ=o,ε→ 0, the relaxation time τtends to zero faster than the diffusion parameter ε. If there exists a priori L∞ bound that is uniformly with respect to ε for the solutionsof a system, then the solution sequence converges to the corresponding equilibrium solution of the system.

研究一般扩散占优的2×2双曲平衡律系统奇异松弛极限，用补偿紧性方法，在松弛时间τ比扩散系数ε趋于零快时，即τ=o，ε→ 0时，得到其解的整体存在性一般框架：如果上述系统的解存在对ε一致的先验L∞估计，则其解序列收敛于上述系统的对应平衡状态解。

Thirdly, under the condition with noαpriori smoothness, in order to obtain the optimal convergence rates, it is not practical to use theαpriori rule. And it is necessary to use the a posteriori stopping rule which not only depends on the error boundδbut also on the perturbed data y~δ.

再次，在没有先验的光滑性信息情况下，为了获得最优收敛速率，利用先验选取准则则变得不再实用，而利用不仅依赖于误差界δ而且依赖于扰动数据y~δ的后验停止准则是必要的。

In addition, the approach is able to avoid the requirement of the upper bound of the first time derivative of the control gain, which is assumed to be known a priori in some of the existing adaptive fuzzy/neural network control schemes.

该方案能够避免现有的一些自适应模糊/神经网络控制器设计中对控制增益一阶导数上界的要求。

Graf, without question, is the greatest women's player in history.

格拉芙，现在，毫无疑问是女子网坛历史上最伟大的选手。

If not, you will have to look around at all your important data.

如果没有，您将需要检查所有的重要数据。
