Model Type and Other Transformations

Convert model type for control design, reduce model order


idfrdFrequency response data or model
idpolyPolynomial model with identifiable parameters
idtfTransfer function model with identifiable parameters
idssState-space model with identifiable parameters
comprealCompute companion state-space realization (Since R2023b)
modalrealCompute modal state-space realization (Since R2023b)
noisecnvTransform identified linear model with noise channels to model with measured channels only
translatecovTranslate parameter covariance across model transformation operations
mergeMerge estimated models
appendGroup models by appending their inputs and outputs
noise2measNoise component of linear identified model
absorbDelayReplace time delays by poles at z = 0 or phase shift
chgTimeUnitChange time units of dynamic system
chgFreqUnitChange frequency units of frequency-response data model
fdelDelete specified data from frequency response data (FRD) models
stackBuild model array by stacking models or model arrays along array dimensions
ss2ssState coordinate transformation for state-space model
