S3 class constructor for storing frequency response data
Description
S3 class constructor for storing frequency response data
Usage
idfrd(respData, freq, Ts, spec = NULL, covData = NULL, noiseCov = NULL)
Arguments
respData |
frequency response data. For SISO systems, supply a vector of frequency response values. For MIMO systems with Ny outputs and Nu inputs, supply an array of size c(Ny,Nu,Nw). |
freq |
frequency points of the response |
Ts |
sampling time of data |
spec |
power spectra and cross spectra of the system output disturbances (noise). Supply an array of size (Ny,Ny,Nw) |
covData |
response data covariance matrices. Supply an array of size (Ny,Nu,Nw,2,2). covData[ky,ku,kw,,] is the covariance matrix of respData[ky,ku,kw] |
noiseCov |
power spectra variance. Supply an array of size (Ny,Ny,Nw) |
Value
an idfrd object
