ControlSystemIdentification

CI codecov Documentation, stable Documentation, latest

System identification for ControlSystems.jl, implemented in Julia.

This package estimates linear statespace models with inputs on the form math \begin{aligned} x^+ &= Ax + Bu + Ke\\ y &= Cx + Du + e \end{aligned} using methods such as N4SID or the prediction-error method, transfer functions on the form math G(z) = \dfrac{B(z)}{A(z)} = \dfrac{b_m z^m + \dots + b_0}{z^n + a_{n-1} z^{n-1} + \dots + a_0} as well as generic nonlinear graybox models math x^+ = f(x, u)

See the documentation for help.

Examples in the form of jupyter notebooks are provided here.

Quick example:

julia using ControlSystemIdentification, ControlSystemsBase Ts = 0.1 G = c2d(DemoSystems.resonant(), Ts) # A true system to generate data from u = randn(1,1000) # A random input y = lsim(G,u).y # Simulated output y .+= 0.01 .* randn.() # add measurement noise d = iddata(y, u, Ts) # package data in iddata object sys = subspaceid(d, :auto) # estimate state-space model using subspace-based identification bodeplot([G, sys.sys], lab=["True" "" "n4sid" ""])
