Vivado設計分為Project Mode和Non-project Mode兩種模式，一般簡單設計中，我們常用的是Project Mode。在本手冊中，我們將以一個簡單的實驗案例，一步一步的完成Vivado的整個設計流程一、新建工程1、打開Vivado 2013.4開發工具，可通過桌面快捷方式或開始菜單中xilinx DesignTools-Vivado 2013.4下的Vivado 2013.4打開軟件，開啟后，軟件如下所示：2、單擊上述界面中Create New Project圖標，彈出新建工程向導，點擊Next.3、輸入工程名稱、選擇工程存儲路徑，并勾選Create project subdirectory選項，為工程在指定存儲路徑下建立獨立的文件夾。設置完成后，點擊Next注意：工程名稱和存儲路徑中不能出現中文和空格，建議工程名稱以字母、數字、下劃線來組成。4、選擇RTL Project一項，并勾選Do not specifty sources at this time，勾選該選項是為了跳過在新建工程的過程中添加設計源文件。點擊Next.IA5、根據使用的FPGA開發平臺，選擇對應的FPGA目標器件。（在本手冊中，以xilinx官方開發板KC705為例，Nexys4開發板請選擇Artix-7 XC7A100TCSG324-2的器件，即Family和Subfamily均為Artix-7，封裝形式（Package）為cSG324，速度等級（Speed grade）為-1，溫度等級（Temp Grade）為C）。點擊Next6、確認相關信息與設計所用的的FPGA器件信息是否一致，一致請點擊Finish，不一致，請返回上一步修改。二、設計文件輸入1、如下圖所示，點擊Flow Navigator下的Project Manager->Add Sources或中間Sources中的對話框打開設計文件導入添加對話框。2、選擇第二項Add or Create Design Sources，用來添加或新建Verilog或VHDL源文件，點擊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
