描述

PFEA111-20

抗锯齿滤波器有助于减少无用奈奎斯特区中的信号内容，否则会产生带内信号混频从而降低动态性能。通常采用LC网络设计抗锯齿滤波器，而且必须要明确规范源阻抗和负载阻抗，以便获得要求的阻带特性和通频带特性。通常采用切比雪夫（Chebyshev）或巴特沃斯（Butterworth）多项式定义滤波器的传递函数。有几种滤波器设计程序有助于简化这个问题，例如NuHertzTechnologies公司的FilterFree4.0或AgilentTechnologies公司的ADS。另外，可以使用滤波器设计手册来找到归一化的原型滤波器参数值，然后根据要求的截止频率和负载阻抗按适当比例进行设计。图5(a)中提供了一个四阶的归一化原型滤波器实例。该滤波器遵循切比雪夫多项式，针对5:1的负载和源阻抗比，理论上可提供小于0.5dB的纹波。对于144MHz的截止频率和600W的负载阻抗，其单端等效网络如图5(b)表示。大多数高速ADC都能够利用差分输入接口完成高动态范围IF采样。因此有必要将单端网络转换为如图5(c)所示的差分网络。在转换为最终的差分网络时，串联阻抗实质上被减半了（见图5(d)）。值得一提的是，试图建立印制电路板（PCB）寄生元件模型以便选择最佳的L和C值是很明智的做法。最终实现的网络采用了比理论值稍低的电感值，以便适应电路印制线的串联电感。应该注意的是图5(c)中的负载现在用图5(d)中的ADC接口代替，包括一个分流电感器和共模偏置电阻器。偏置电阻为每个差分输入端提供所需的直流偏置，并且与原来的跟踪阻抗和谐振分流电感器结合起来共同为负载提供滤波器。
    考虑网络的品质因数Q是很重要的。负载和源阻抗的比例越大，就越需要注意元件Q值和布线的寄生效应。通常需要采用一些经验性的反复试验法来优化网络接口，以达到噪声和失真性能的最佳组合。采用能精确地捕获实际L和C寄生效应的元件模型对网络响应进行仿真是较为合适的。

主营：本特利，英维思，伍德沃德，福克斯波罗、西屋、瑞恩、施耐德莫迪康、ABB、AB、西门子、摩托罗拉、GE发那科、安川、博世力士乐，ACSO，力士乐等各大品牌的DCS系统配件，机器人系统配件，大型伺服系统备件。

先介绍几点经验。
1、先通读一遍“系统手册”（不管能不能看懂，先了解个大概，以便学习编程时查找）；
2、由位控逻辑入手，逐渐增加定时、计数等条件，把或、与、非关系理顺；
3、进而练习整数运算、实数运算、类型转换；
4、量程转换、PID调节回路的建立及P、I、D参数的理解（最好是有个物理回路验证，比如变频器+电机+测速传感器）；
5、循环、顺序、跳转等程序控制（尽量避免跳转，非跳不可时也是跳的越近越好）；
6、中断、通讯、位置控制....

本人以ABB工业机器人配件DSQC系列和Motorola MVME系列，GE 卡件 模块 驱动器系列为主攻。各位电工朋友可根据自己的条件选择适合自己的PLC品牌，由于PLC的基本框架大同小异，学会一种至于其它的学习起来也就简单了。
