I am looking for Compact RIO system for PID control

[numhana]

Hi all,

I am looking for the CompactRIO system for PID control.
My system acquires two input data (0-10V) from two displacement sensors and sends one output signal (0-10V) to piezo-actuator at every step. And my target is the short settling time and the low overshoot.

I think that I need fast control system. So I am interested in CompactRIO. But I am not familiar with this sytem. Could you recommend the good control system for me?

The one important thing is that the time limiting step of my system is Piezo actuator (it's natural freq is 20kHz.) CompactRIO is much faster than the Piezo-actuator. I am not sure whether CompactRIO is good to my system or not.

Here is the CompactRIO system which I am interested in:

i) CompactRIO Reconfigurable Embedded System: cRIO-9004
ii) CompactRIO Reconfigurable Chassis: cRIO-9101
iii) I/O Module : AI : cRIO-9215 AO: cRIO-9263

Thank you so much,

Sungjin

Hello Sungjin,

CompactRIO should work great for your PID control system. Those I/O modules are the correct voltage range and the 1M gate FPGA backplane will be plenty for a single PID controller. You'll probably be able to get loop rates around 100kHz for analog PID control.

Keep in mind that the LabVIEW FPGA module includes PID examples that will cut down your development time considerably.

Regards,
Vineet
