In this paper a method for studying process dynamics will be presented. The method is based on statistical time series modelling called multivariate autoregressive modelling. The proposed method can be used for trouble-shooting diagnostics and control system modelling applications. After the multivariate autoregressive model is identified the dynamics of the system can be analyzed with the model. The model parameters are used for determination of power spectrum estimates, transfer functions with step responses and noise source contributions. Those parameters can be used also for simulation purposes. The result of the present study suggests effectiveness and usefulness of the method as a tool in process dynamics research.
