How to apply a control algorithm with softmotion?

[Jingyang_Yan]

Hi,

I'm using compactRIO and SoftMotion Module to control a motor.

I'm wondering whether I can apply advanced control algorithms in this system, like neural network control or H-infinity control.

I found something maybe useful here http://www.ni.com/white-paper/2953/en/#toc6  but i can't open the page of No.6 View Interactive Tutorial on NI SoftMotion Technology 

Can anyone provide some information about this kind of applications?

My hardware is compactRIO-9049, LabVIEW 2017 NI SoftMotion Module 17.0.1. My motors are Yaskawa Sigma-7. For now, I could apply a simple application such as straight-line move.

Many Thanks,

Jingyang

Hey Jingyang,

Could you explain what you mean by neural network control? I attached a link to the SoftMotion manual below, It will give you a little more information about using the LabVIEW NI SoftMotion Module to create a customized hardware interface.

Hi Austin,

In slide 25 of attached pdf, you could find a LQR control loop. Is it possible for me to get this project?

I believe this would help me a lot. For neural network control, you could consider it as a control algorithm just like LQR.

Thanks,

Jingyang

Hey Jingyang

The LQR control loop on page 25 is part of the Control Design and Simulation Module, I attached some links to it below. You could always evaluate that module and see if it has what you need in it. I also attached some links that will help give you a better idea of how SoftMotion works over Ethercat.
