model
Syntax
Description
Input Arguments
nlsys
— Nonlinear ARX model
idnlarx
object
Nonlinear ARX model, specified as an idnlarx
object.
Output Arguments
spec
— Operating point specification
operating point specification object
Operating point specification, used to determine an operating
point of the idnlarx
model using findop
,
returned as an object containing the following:
Input
— Structure with fields:Field Description Default for Each Input Value
Initial guesses or fixed levels for the values of the model inputs, specified as a vector with length equal to the number of input signals. 0
Min
Minimum value constraints on the model inputs, specified as a vector with length equal to the number of input signals. -Inf
Max
Maximum value constraints on the model inputs, specified as a vector with length equal to the number of input signals. Inf
Known
Known value indicator, specified as a logical vector with length equal to the number of input signals and with the following values:
true
—findop
will set the corresponding input signal toValue
.false
—findop
will estimate the corresponding input signal usingValue
as an initial guess.
true
Output
— Structure with fields:Field Description Default for Each Output Value
Initial guesses for the values of the model outputs, specified as a vector with length equal to the number of output signals. 0
Min
Minimum value constraints on the model outputs, specified as a vector with length equal to the number of output signals. -Inf
Max
Maximum value constraints on the model outputs, specified as a vector with length equal to the number of output signals. Inf
