前馈补偿伺服回路误差

PEN

本文最近在美国的Hydraulics＆Pneumatics杂志上发表。
它由杰克约翰逊撰写，他是MSOE的教授。 后来他开办了自己的液压咨询公司。 他教过派克流体动力液压系统工程师。 杰克约翰逊创造了新知识，而不仅仅是复制别人。

这篇文章是英文的。 Jack Johnson描述前馈的方式与Delta Computer Systems或Rockwell实现前馈不同。 它更接近数字液压缸必须使用的脉冲补偿技术。 杰克约翰逊没有解释如何实现加速或挺举前馈。

Feed-Forward Compensates for Servo Loop Errors
This article was recently printed in the Hydraulics & Pneumatics magazine in the US.
It is written by Jack Johnson who was a professors at MSOE.  Later he started his own hydraulic consulting company.  He taught Parker Fluid Power hydraulic systems engineers.  Jack Johnson  created new knowledge instead of just copying others.

The article is in English.  The way Jack Johnson describes feed-forwards is not the same we Delta Computer Systems or Rockwell implements feed-forwards.  It is closer to the pulse compensation technique that digital hydraulic cylinders must use.  Jack Johnson does not explain how to implement acceleration or jerk feed-forward.

为方便大家探讨这个主题，我把PEN教授说的这个文档上传了附件
For easy to commulacate this topic, I have upload the attachment document mentioned by Professor PEN.

如果是变负载工况或马达控制，单一的前馈很难使用，有时候很难确定前馈值
