Configuring the PID (FPGA) Express VI

[JKSH]

Hello,

I'm implementing a control system using the PID (FPGA) Express VI. I was wondering if crucial to provide the correct sampling time: Does the Express VI's functionality depend on it, or is it only for calculating the initial quantized gains?

Hi there, The sampling time directly affects the integral and the derivative gain (see the formula at the details section over here). Unless you are doing a proportional control (only) I don't see a problem. For more reference check this other link.
