ijab description

iJab是一款可定制的即时通讯工具,支持多种工作模式,可通过修改ijab_config.js文件来调整客户端类型、主题样式、登录设置等参数。本文档详细介绍了如何配置这些参数以满足不同的应用场景。

======iJab parameters description===========

iJab has many parameters to custome and config it and let me describe them
to you.

You could find them in ijab_config.js file.

var iJabConf =
{
client_type:"xmpp",
app_type:"bar", // iJab would support bar/stand-alone/live-support modes in future version, now you just could set this to bar
theme:"standard", // in iJab directory you could find a standard directory which includes css file and image for iJab, you cuold write your own theme.
avatar_url:"http://www.ijab.im/avator?user={username}", // iJab would replace {username} with userid in iJab to get user's photo from your website, you should write this script in your
// website yourself which should return a image content
enable_roster_manage:true, // let user could add/delete his roster or not
enable_talkto_stranger:true, // let user talk to users not in his roster list or not
expand_bar_default:false, // expand bar by default or not
enable_login_dialog:true, // Open login dialog while click Chat button while iJab disconnected
hide_online_group:false, // Show online special group or not
disable_option_setting:false, // Disable option setting button or not
disable_msg_browser_prompt:false, // Disable showing receiving message notification on brower window title or not
xmpp:{
domain:"ijab.im", // Domain that your XMPP server served
http_bind:"/http-bind/", // http-bind address, you should config correct rewrite rules or proxy for http-bind request to your http-bind server
host:"", // You XMPP server host, leave it be empty if you don't use third-party http-bind server
port:5222, // XMPP server listening port(not http-bind port)
server_type:"ejabberd", // iJab supports ejabberd/openfire/tigase now
auto_login:false, // Enable iJab auto login with your website or not
none_roster:false, // Make iJab not get roster from XMPP server
get_roster_delay:true, // Let iJab get roster when clicking Chat button, not get it soon after login
username_cookie_field:"username", // If enable auto login, iJab would try to get username from cookie use this key
token_cookie_field:"SID", // If enable auto login, iJab would try to get auth token from cookie use this key
anonymous_prefix:"", // If enable anonymouse login on your XMPP server, set how to make anonymouse username
max_reconnect:3, // If enable auto login, how many times iJab would try to login to XMPP server
enable_muc:true, // Enable MUC(Group Chat) or not
muc_servernode:"conference.ijab.im", // MUC component JID
vcard_search_servernode:"vjud.ijab.im", // Vcard search component JID
gateways: // Configure transports here
[

基于STM32 F4的永磁同步电机无位置传感器控制策略研究内容概要:本文围绕基于STM32 F4的永磁同步电机(PMSM)无位置传感器控制策略展开研究,重点探讨在不依赖物理位置传感器的情况下,如何通过算法实现对电机转子位置和速度的精确估计与控制。文中结合嵌入式开发平台STM32 F4,采用如滑模观测器、扩展卡尔曼滤波或高频注入法等先进观测技术,实现对电机反电动势或磁链的估算,进而完成无传感器矢量控制(FOC)。同时,研究涵盖系统建模、控制算法设计、仿真验证(可能使用Simulink)以及在STM32硬件平台上的代码实现与调试,旨在提高电机控制系统的可靠性、降低成本并增强环境适应性。; 适合人群:具备一定电力电子、自动控制理论基础和嵌入式开发经验的电气工程、自动化及相关专业的研究生、科研人员及从事电机驱动开发的工程师。; 使用场景及目标:①掌握永磁同步电机无位置传感器控制的核心原理与实现方法;②学习如何在STM32平台上进行电机控制算法的移植与优化;③为开发高性能、低成本的电机驱动系统提供技术参考与实践指导。; 阅读建议:建议读者结合文中提到的控制理论、仿真模型与实际代码实现进行系统学习,有条件者应在实验平台上进行验证,重点关注观测器设计、参数整定及系统稳定性分析等关键环节。
