delayest - Estimate time delay (dead time) from data
Syntax
nk = delayest(Data)
nk = delayest(Data,na,nb,nkmin,nkmax,maxtest)
Description
Data is an iddata object
containing the input-output data. It can also be an idfrd object
defining frequency-response data. Only single-output data can be handled.
nk is returned as an integer or a row vector
of integers, containing the estimated time delay in samples from the
input(s) to the output in Data.
The estimate is based on a comparison of ARX models with different
delays:
The integer na is the order of the A polynomial
(default 2). nb is a row vector of length equal
to the number of inputs, containing the order(s) of the B polynomial(s)
(default all 2).
nkmin and nkmax are row
vectors of the same length as the number of inputs, containing the
smallest and largest delays to be tested. Defaults are nkmin = 0 and nkmax = nkmin+20.
If nb, nkmax, and/or nkmin are
entered as scalars in the multiple-input case, all inputs will be
assigned the same values.
maxtest is the largest number of tests allowed
(default 10,000).
