Parameter identification of transfer functions using MATLAB
Mato Fruk, Goran Vujisić, Tomislav Špoljarić · 2013
This paper describes a procedure for identifying the transfer function parameters by using Matlab's System Identification Toolbox (SIT). The procedure is explained for obtaining numerical data using a digital oscilloscope in a format suitable for loading the data into Matlab and processing within the SIT. The measured data series connected RLC circuits were analyzed. Also, using the speed response of separately excited DC motor with and without smoothing coil was measured, and transfer functions were obtained.
