Hi all,

I have struggling on my first trial data simulation by using function block algorithm Lead (LD) block. The function block equation is transferred from s-domain to time domain and using time domain equation to simulate in Excel. The result is output are trending into the same direction, but my output signal is difference from real output in DCS even are the same gain, derivative time, and real data input. Please have a look details in the link below:

I am appreciate if anyone can advise me how to do correctly.

The derivative action is achieved by multiplying the Fouier amplitude by frequency and then taking the inverse.

Good luck
