<div><div class='shrinkable-quote'><br>> Hello,
<br>>
<br>> I am looking for a Scilab software which is similar to Matlab System ID tool
<br>> box.
<br>>
<br>> I would like to obtain values of parameters, Tau, K and Td for following
<br>> first order delay + Dead time model from time series data.
<br>> ymodel = (K/(Tau*s+1))*exp(-Td*s)*u
<br>> ymodel: process output, u: process input
<br>> SISO continuous time
</div>.
</div>What is s?
<br>What's the input variable: s or u? And is the other a known parameter?
