The main aim of this book is to present a unified, systematic description of basic and advanced problems, methods and algorithms of the modern con- trol theory considered as a foundation for the design of computer control and management systems. The scope of the book differs considerably from the topics of classical traditional control theory mainly oriented to the needs of automatic control of technical devices and technological proc- esses. Taking into account a variety of new applications, the book presents a compact and uniform description containing traditional analysis and op- timization problems for control systems as well as control problems with non-probabilistic models of uncertainty, problems of learning, intelligent, knowledge-based and operation systems – important for applications in the control of manufacturing processes, in the project management and in the control of computer systems.

解读 5G 八大关键技术 【摘要】5G 不是一次革命,5G 是 4G 的延续,我相信 5G 在核心网部分不会有太 大的变动,5G 的关键技术集中在无线部分。 在进入主题之前,我觉得首先应该弄清楚一个问题:为什么需要 5G?不是因 为通信工程师们突然想改变世界,而炮制了一个 5G。是因为先有了需求,才有了 5G。什么需求? 未来的网络将会面对:1000 倍的数据容量增长,10 到 100 倍的无线设备连接, 10 到 100 倍的用户速率需求,10 倍长的电池续航时间需求等等。坦白的讲,4G 网络无法满足这些需求,所以 5G 就必须登场。 但是,5G 不是一次革命。5G 是 4G 的延续,我相信 5G 在核心网部分不会有 太大的变动,5G 的关键技术集中在无线部分。虽然 5G 最终将采用何种技术,目前 还没有定论。不过,综合各大高端论坛讨论的焦点,我今天收集了 8 大关键技术。 当然,应该远不止这些。 1.非正交多址接入技术 (Non-Orthogonal Multiple Access,NOMA) 我们知道 3G 采用直接序列码分多址(Direct Sequence CDMA ,DS-CDMA) 技术,手机接收端使用 Rake 接收器,由于其非正交特性,就得使用快速功率控制 (Fast transmission power control ,TPC)来解决手机和小区之间的远-近问题。 而 4G 网络则采用正交频分多址(

应用无迹卡尔曼滤波算法(UKF)进行锂电池的SOC估计,采用Thevenin二阶RC等效电路模型,对HPPC电池脉冲充放电实验数据进行Matlab处理,得到较为准确的模型.通过在Matlab中编写算法程序,对不同工况的估计值与实际值进行误差估算及对比分析,通过此算法进行SOC估计,得到该算法可有效降低系统误差并纠正SOC的初值偏差.The non trace Calman filter (UKF) is applied to the SOC estimation of lithium battery. The Thevenin two order RC equivalent circuit model is used to process the HPPC battery pulse charge discharge experimental data by Matlab processing, and a more accurate model is obtained. By writing algorithm program in Matlab, the error estimation and comparison analysis of the estimated value and actual value of different states are carried out, and the SOC estimation is carried out by this algorithm. The algorithm can effectively reduce the system error and correct the initial value deviation of the SOC.

Vivado设计分为Project Mode和Non-project Mode两种模式,一般简单设计中,我们常用的是Project Mode。在本手册中,我们将以一个简单的实验案例,一步一步的完成Vivado的整个设计流程一、新建工程1、打开Vivado 2013.4开发工具,可通过桌面快捷方式或开始菜单中xilinx DesignTools-Vivado 2013.4下的Vivado 2013.4打开软件,开启后,软件如下所示:2、单击上述界面中Create New Project图标,弹出新建工程向导,点击Next.3、输入工程名称、选择工程存储路径,并勾选Create project subdirectory选项,为工程在指定存储路径下建立独立的文件夹。设置完成后,点击Next注意:工程名称和存储路径中不能出现中文和空格,建议工程名称以字母、数字、下划线来组成。4、选择RTL Project一项,并勾选Do not specifty sources at this time,勾选该选项是为了跳过在新建工程的过程中添加设计源文件。点击Next.IA5、根据使用的FPGA开发平台,选择对应的FPGA目标器件。(在本手册中,以xilinx官方开发板KC705为例,Nexys4开发板请选择Artix-7 XC7A100TCSG324-2的器件,即Family和Subfamily均为Artix-7,封装形式(Package)为cSG324,速度等级(Speed grade)为-1,温度等级(Temp Grade)为C)。点击Next6、确认相关信息与设计所用的的FPGA器件信息是否一致,一致请点击Finish,不一致,请返回上一步修改。二、设计文件输入1、如下图所示,点击Flow Navigator下的Project Manager->Add Sources或中间Sources中的对话框打开设计文件导入添加对话框。2、选择第二项Add or Create Design Sources,用来添加或新建Verilog或VHDL源文件,点击Next
