Abstract :
Closed-loop identification of the multi-input multi-output (MIMO) process is studied. Models of coprime factors and their error bounds in the frequency domain are estimated using a stochastic method. Simple solutions are proposed under different conditions of the feedback controller. For each coprime factorization it is necessary to solve two open-loop identification problems, which can be done using a stochastic approach. The corresponding Bezout identity can be used for model validation
