Questions tagged [system-identification]

Questions about "system identification" in the sense of control theory.

Questions about "system identification" in the sense of control theory. I.e. how to calibrate a model for the behaviour of a dynamic system.

See also https://en.wikipedia.org/wiki/System_identification

For questions on how to uniquely identify a client system, e.g. based on hardware serial numbers, the hardware-id tag shall be used.

Multiexperiments in iddata function from Matlab's system ID toolbox

I am trying to evaluate with iddata (INFO) in matlab, a number of N_E experiments. I already computed and have as cell arrays of size 1xN_E the outputs and inputs, y and u respectively. Every entry of the cell arrays y and u is a vector of length…

How to get transfer function (approximation) of unknown system in matlab/simulink?

I have a unknown system in simulink model (non-linear) and I dont know how to get a TF which will describe it in certain interval of input data. Im sorry that im asking such abstract question but im really lost. I tried…

Quadratic programming with linear equality constraints in Matlab

I have to identify an ARX under some linear constraints, this means that I have a quadratic programming with linear equality constraints problem. One way is to use the following equations in the red boxes. A possible disadvantage in this case is…

Does normalization affect on system identification result?

suppose a nonlinear system with 3 input-3 output,in-out data has been logged on a experiment at the same time,if we do/do not a normalization(take data between -1 and 1), on in-out data ,is result the same,after a black-box(Nonlinear arx…
