System identification

System identification is the art and science of using data in the process of building a model of a system.

Model calibration

For calibration of parameters in ModelingToolkit models, see JuliaSimModelOptimizer.jl.

Linear model estimation

For estimation of LTI models, such as statespace models or transfer functions, using techniques such as the prediction-error method, subspace-based identification and frequency-domain fitting, see ControlSystemIdentification.jl.

For an example of designing an MPC controller using a model estimated from data, see MPC with model estimated from data.
