Please check the following product of SIEMENS,the well designed functions with good English documents.The functions are suitable for PID applications: http://support.automation.siemens.com/WW/view/en/1137082 Check the following functions: 2.1.1 A_DEAD_B: Adaptive Dead Band If you actually using the analog input at the PV of a PID controller and the ERROR=SP-PV is fed to algorithm.This may cancel bad effect of flactuation on the output. 2.1.9 LAG1ST: First-Order Lag Element First order filter,used to convert steps to smooth exponential curves. regards |

Hi, hdhosseini I used the block attached by Late in the above post. I called that block in Ob34. I have F_tau=10. I used a trial & error method to get the good filetering. In the begining I filter only 2 sec, then 3.5 sec then 5 sec and finally 10sec if found to be satisfactory with my Flow Noise filtering. See the attachement. |

That's what I was looking for and I've lost hope! Does this "average" have a mathematical name? |
