It is shown that under the supervision of the monitoring functions, the switching of control signal will stop after a finite number of switching and the tracking error will converge to a residual set that can be made arbitrarily small by choosing some design parameters sufficiently small.

进而证明，当被控对象相对阶大于1、高频增益符号未知时，在监控函数的监测下，相关控制信号经至多有限次切换后将停止切换，跟踪误差将收敛到一个残集内，且该残集可通过减小某些设计参数而变得任意小。

An index is calculated as the ratio of the economic loss estimated by using the continuity method and the economic loss calculated by using the discrete method with different seismic performance levels.The minimum number of performance levels is considered as the rational result when the index is within a prescribed small range.

这在1994年美国北岭、1995年日本阪神和1999年台湾集集地震中，由于不能有效地控制结构破坏而带来了巨大的经济损失[4-5]，远远超出了预先的估计。

A differential method for capacity control is presented based on the analysis of the capacity of learning machines.

The algorithm runs on the sink node and the connected dominating set educed from the algorithm forms the virtual backbone of the network. Because the algorithm gets the global information and the information is general, the size of the connected dominating set got from the centralized heuristic algorithm is smaller than that of distributed heuristic algorithm.

本文算法在中心控制或管理节点上运行，求得的连通支配集构成无线传感器网络的虚拟骨干网，并且由于算法采用网络的全局信息，获得的信息量较为全面，所以求得的连通支配集的规模相对于分布式算法更小。

It was applied to model and predict the variables of the mycetozoan fed-batch process. The result has shown that the structure of this kind of neural network model is simple, explicable and the convergent speed is much quicker.

为此，结合模糊粗糙集和智能控制的理论，充分利用模糊粗糙集和神经网络两者的优点，提出了一种新型的网络—模糊粗糙神经网络实现对发酵过程的建模和状态估计。

Dual mode predictive control method is proposed for reducing on-line burden. The proposed method applies the ellipsoid invariant set to the terminal set.

该方法将时滞系统的不变椭圆集应用于预测控制的终端约束集，保证了输入受限系统的可行性和稳定性。

When the predictive states are in invariant ellipsoid set, the off-line state-feedback law is adopted. Thus, computational burden is reduced.

最后将时滞系统的滑模面作为预测控制的不变集，扩大了终端约束集，有效缩短了预测时域。

During the deseign of control software of MODEN , we introduce in detail a few function such as initialization , dialing , responsion and hanging up etc , deseign and debug the communication procedure .

专门使用于控制调制解调器的指令集被称为"AT指令集"，对MODEN的所有操作都可以通过给MODEN发送ASCII字符串来实现，MODEN在收到AT命令后，先对命令进行判断，接着分析和执行命令缓冲区中的命令，最后以自身的ASCII字符对命令作出响应。

Meanwhile, we have gotten stability for the subdifferential of cone efficient point sets and cone weakly efficient point sets of multiobjective programming with respect to perturbation of cone respectively.

对于局部凸拓扑向量空间的多目标规划问题，本文研究并得到当确定空间序的控制锥受扰动，它们的锥有效点集和锥弱有效点集分别在锥次微分和锥弱次微分意义下的稳定性结果。
