  • matlab 7.0软件下载(免费破解版)

    matlab 7.0软件下载(免费破解版):Matlab作为美国 MathWorks公司开发的用于概念设计,算法开发,建模仿真,实时实现的理想的集成环境。是目前最好的科学计算类软件。 作为和Mathematica、Maple并列的三大数学软件。其强项就是其强大的矩阵计算以及仿真能力。要知道Matlab的由来就是Matrix + Laboratory = Matlab,所以这个软件在国内也被称作《矩阵实验室》。 每次MathWorks发布Matlab的同时也会发布仿真工具Simulink。在欧美很多大公司在将产品投入实际使用之前都会进行仿真试验,他们所主要使用的仿真软件就是Simulink。 Matlab提供了自己的编译器:全面兼容C以及Fortran两大语言。 所以Matlab是工程师,科研工作者手上最好的语言,最好的工具和环境。 注:由于软件较大,请在下载地址上,右键选择迅雷或快车进行下载。否则可能会出现服务器忙。限制了同时下载人数,请下载时等待时机即可。

  • WP264-在数字视频应用中使用CPLD

      The CoolRunner-II CPLD is a highly uniform family of fast, low-power devices. Theunderlying architecture is a traditional CPLD architecture, combining macrocells intofunction blocks interconnected with a global routing matrix, the Xilinx AdvancedInterconnect Matrix (AIM). The function blocks use a PLA configuration that allowsall product terms to be routed and shared among any of the macrocells of the functionblock.

  • 赛灵思电机控制开发套件简介(英文版)

      The power of programmability gives industrial automation designers a highly efficient, cost-effective alternative to traditional motor control units (MCUs)。 The parallel-processing power, fast computational speeds, and connectivity versatility of Xilinx® FPGAs can accelerate the implementation of advanced motor control algorithms such as Field Oriented Control (FOC)。   Additionally, Xilinx devices lower costs with greater on-chip integration of system components and shorten latencies with high-performance digital signal processing (DSP) that can tackle compute-intensive functions such as PID Controller, Clark/Park transforms, and Space Vector PWM.   The Xilinx Spartan®-6 FPGA Motor Control Development Kit gives designers an ideal starting point for evaluating time-saving, proven, motor-control reference designs. The kit also shortens the process of developing custom control capabilities, with integrated peripheral functions (Ethernet, PowerLink, and PCI® Express), a motor-control FPGA mezzanine card (FMC) with built-in Texas Instruments motor drivers and high-precision Delta-Sigma modulators, and prototyping support for evaluating alternative front-end circuitry.

  • 基于EKF的异步电机直接转矩控制系统

    为了提高直接转矩控制(DTC)系统定子磁链估计精度,降低电流、电压测量的随机误差,提出了一种基于扩展卡尔曼滤波(EKF)实现异步电机转子位置和速度估计的方法。扩展卡尔曼滤波器是建立在基于旋转坐标系下由定子电流、电压、转子转速和其它电机参量所构成的电机模型上,将定子电流、定子磁链、转速和转子角位置作为状态变量,定子电压为输入变量,定子电流为输出变量,通过对磁链和转速的闭环控制提高定子磁链的估计精度,实现了异步电机的无速度传感器直接转矩控制策略,仿真结果验证了该方法的可行性,提高了直接转矩的控制性能。 Abstract:  In order to improve the Direct Torque Control(DTC) system of stator flux estimation accuracy and reduce the current, voltage measurement of random error, a novel method to estimate the speed and rotor position of asynchronous motor based on extended Kalman filter was introduced. EKF was based on d-p axis motor and other motor parameters (state vector: stator current, stator flux linkage, rotor angular speed and position; input: stator voltage; output: staror current). EKF was designed for stator flux and rotor speed estimation in close-loop control. It can improve the estimated accuracy of stator flux. It is possible to estimate the speed and rotor position and implement asynchronous motor drives without position and speed sensors. The simulation results show it is efficient and improves the control performance.

  • XAPP904 - CoolRunner-II特性LCD模块接口

      There are many manufacturers of dot matrix LCD modules. However, most of these displaysare similar. They all have on-board controllers and drivers capable of displaying alpha numericsand a wide variety of other symbols (including Japanese "Katakana" characters). The internaloperation of LCD controller devices is determined by signals sent from a central processing unit(in this case, a CoolRunner-II CPLD).
