| Abstract: | The aim of the paper is to study the Subspace State Space System Identification method based on state space model and to introduce the method's basic theory. Furthermore, the method was improved by combined with AIC(Akaike Information Criterion). The comparison between the two methods were made via simulation. The results show that the improved algorithm is feasible and superior and can be used to identify the order of system correctly, and it has a wide application in industrial processes. |
