PID simulation

krishna_das — Wed, 10 Aug 2022 12:17:26 GMT

Hello I am new in labview, I want to simulate this pid controller , using the values of kp = 12, Ki= 12.6316 and Kd = 7.6 , on the basis of mentioned gain values ti and td are calculated.

On running it I am getting such response

But this is not correct as , implemented the same thing in scilab and got response below.

Below is implementation in scilab

Please help..

Hi All

I want to do time domain analysis of below system, I want to find settling time, rise time , etc.

Please help

write down all the formulas you need to determine your data.
implement those formulas in LabVIEW!

Where are you stuck?

Do you really have a plant where you use PI gains of 2e-9 and 1e+20???

Yes I do have a plant , I want to measure rise time , settling time, peak overshoot , peak time etc for this

that is T i = 1e+20 , means Ki is set to zero.

Dear krishna_das,

https://www.intechopen.com/chapters/75407 I've found this article that is about labview data analysis functions. You can find what could help your case and use it. I guess you should do the analysis on the cluster that is depicted as a xy graph.
