切换

Take a simple player application for example, which allows the user to play a media file by either clicking a play/pause toggle button or selecting a play/pause entry from a menu bar.

像是一个简单的播放软件，它允许用户播放媒体通过点击播放/暂停切换按钮或选择一个播放/暂停从菜单栏项文件。

Unlike the common hot standby mode with different software between master server and slave server, in this system, master server and slave server are equipotent. It confirmed the identities of master server and slave server according to start-up sequence, and it also has the following functions: synchronous renewal of the configuration files, synchronous storage of data, heartbeat detection, fault diagnosis and server switch.

与一般的在主从服务器端安装不同软件的双机热备方式不同，本系统的主从服务器具有对等性，根据主从采集服务器的启动顺序来确定主从机的身份，并且具有配置文件的同步更新、数据的同步存储、心跳检测、故障诊断与双机切换等功能。

Secondly, the error equation is equivalent to the discrete switched system related to the hop count of the wireless transmission, and the stability of the error system is proved.

然后将误差方程等效为与无线传输跳数相关的离散切换系统，并证明了误差系统的稳定性。

Meanwhile, the outlets of the system are predicted by the feedback adjusting method. According as whether the system response is in the range of the error band and whether the model prediction output exceeds this error band.

同时，用带反馈校正的模型预测作系统输出预测，根据系统响应和系统预测值是否在给定误差范围内来共同决定控制量在限幅值与内模控制器输出值之间进行在线智能切换。

This paper presents a new type control method-the mixture trending law,which based on the exponential trend law,variable rate trend law and the saturated function.

在分析2种控制不足的基础上，提出了基于指数趋近-变速趋近-饱和切换函数的混合趋近控制律，并进行了对比仿真试验分析和实验研究。

A new discrete reaching law is presented to improve the reaching process of discrete exponential reaching law.The discrete-time variable structure control system designed by this reaching law can not only weaken the chattering and control the system state approach to zero diminishingly,but also keep the basic property of quasi-sliding mode which can cross the switching surface step by step.This method improves the reaching process and enhances the control quality of the control system.

为了改善离散指数趋近律的趋近过程，提出了一种新的趋近律，利用该趋近律设计的变结构控制器，不仅能够大幅度削弱抖振，使系统运动最终趋于原点不存在稳态振荡，而且能使系统的准滑动模态保持步步穿越切换面的基本属性，有效地改善了趋近过程，提高了控制品质。

In this paper, the exponential stability and stabilization of linear switched system under certain assumptions are mainly studied.
