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

Abstract: A sliding mode observer and fractional-order phase-locked loop (FO-PLL) method is proposed for the sensorless speed control of a permanent magnet synchronous motor (PMSM).The saturation function is adopted in order to reduce the chattering phenomenon caused by the sliding mode observer. In this proposed FO-PLL, method, a regulable fractional order r is involved, which means that the FO-PLL provides an extra degree of freedom. In fact, the conventional phase-locked loop (PLL) applied in sensorless PMSM control can be seen as a special case of the proposed FO-PLL. By selecting a proper fractional order r a better performance may be achieved. The computer simulation results demonstrate the effectiveness of the proposed method.Key words: fractional calculus; fractional order phase-locked loop; sensorless control; sliding mode observer; permanent magnet synchronous motor; speed controll

Spartane-6 LXand LXT FPGAs are available in various speed grades, with -3 having the highest performance. The DC and AC electrical parameters of the Automotive XA Spartan-6 FPGAs and Defense-grade Spartan-6Q FPGAs devices are equivalent to the commercial specifications except where noted. The timing characteristics of the commercial(XC)-2 speed grade industrial device are the same as for a-2 speed grade commercial device. The -2Q and -3Q speed grades are exclusively for the expanded(Q) temperature range. The timing characteristics are equivalent to those shown for the-2 and-3speed grades for the Automotive and Defense-grade devices.Spartan-6 FPGA DC and AC characteristics are specified for commercial (C), industrial (), and expanded (Q) temperature ranges. Only selected speed grades and/or devices might be available in the industrial or expanded temperature ranges for Automotive and Defense-grade devices.

German universities and scientists have repeatedly set the intermational standard in drive technology. Identification and active compensation of natural frequencies in oscillatory mechanics, status controls with monitoring structures incorporating acceleration sensors, adaptive compensation of measurement system deficiencies, self-adjusting detent torque compensation… everything invented with only a single aim in mind: to continue improv-ing the motion control, dynamics, precision and processing speed of your machines. For the industrial applicabability of this technology scientific publications in proceedings and laboratory test rigs are not enough. These features consequenty need to be converted into cost-efficient and easily manageable products. That 's exactly what we have done.So in future, if you should need more than today ' smarket can offer you, now everything isgoing to be alright. With our new high-performance ServoOne drive series you will experi-ence
