conference paper description
The aim of this paper is to suggest a new approach in time-delay identification. With the focus on the value of the delay it utilizes known system parameters for model based predictions in order to estimate the most precise value of the time-delay. This method was further extended by applying a modified internal model based on smaller sampling value which enables to receive results with greater precision than a single original sampling step. The suggested procedure therefore grants a deeper insight into the development of the time-delay and influencing effects from outer signals. The identification algorithm was realized in the MATLAB environment, which was also used for simulations verifying precision of the approach.
