greyest
Linear greybox model estimation
Syntax
sys = greyest(data,init_sys)
sys = greyest(data,init_sys,opt)
[sys,x0] = greyest(___)
Description
estimates a linear greybox model, sys
= greyest(data
,init_sys
)sys
, using time or frequency
domain data, data
. The dimensions of the inputs and outputs of
data
and init_sys
, an
idgrey
model, must match. sys
is an
identified idgrey
model that has the same structure as
init_sys
.
estimates a linear greybox model using the option set, sys
= greyest(data
,init_sys
,opt
)opt
, to
configure the estimation options.
[
returns the value of the initial states computed during estimation. You can use this
syntax with any of the previous inputargument combinations.sys
,x0
] = greyest(___)
