MRAS在油膜轴承动态特性辨识中的应用

将模型参考自适应系统（ＭＫＡＳ）用于辨识轴承的８个线性化系数。每个轴承座在水平和垂直方向均简化为质量－弹簧－阻尼系统。在多跨转子系统的在线辨识和诊断中，这种方法有其独特的优点。此方法的可行性经计算机模拟和实验得到证明。     

Using evolutionary computation to solve problems in nonparametric regression

This paper studies evolutionary mechanism of parameter selection in the construction of weight function for Nearest Neighbour Estimate in nonparametric regression. Construct an algorithm which adaptively evolves fine weight and makes good prediction about unknown points. The numerical experiments indicate that this method is effective. It is a meaningful discussion about practicability of nonparametric regression and methodology of adaptive model-building.

ROBUST H∞ CONTROL FOR UNCERTAIN NONLINEAR SYSTEMS

This paper studies the robust H∞ disturbance attenuation with internal stability for uncertain nonlinear control systems. By adding one power integrator technique, this paper designs a explicit smooth robust dynamic feedback law while rejecting the disturbance to any specified degree of accuracy. Further, the example and simulation results show the effectiveness of the proposed schemes.     

Kinetic analysis of self-condensing vinyl polymerization with unequal reactivities

The distribution function of the hyperbranched polymers formed from the self-condensing vinyl polymerization with unequal reactivities was derived and the differential equations for the second moments are established, based on the variable of the conversion of B^＊ groups. The various average degrees of branching can be designed by suitable values of reactivities ratio （r） and the conversion of A group （x）. In order to reach the maximum degree of branching at a specified x, r needed is dependant on the value of x. The higher the x, the less the r needed is for the maximum value of degree of branching. At the end of the reaction, the maximum degree of branching reaches 0.5 with r=2.59.

快速暂态过电压的形成机制与抑制方法

为了研究封闭式组合电器(GIS)中隔离开关操作引起的快速暂态过电压的产生机制，采用了探求“激发模式”的思想方法．“激发模式”的分析方法可以抓住产生快速暂态过电压的主要因素，且所生物理图像清晰，非常有益于直接指导GIS的结构设计．通过分析，发现了高压套管电容效应和导体波阻抗跃变2种“激发模式”，由此提出了一种新的快速暂态过电压抑制方法．该方法是在GIS终端加上波阻抗较小的一段导体，以抑制快速暂态过电压．分析表明，这种方法对于抑制GIS端口处的快速暂态过电压是很有效的。
