Abstract
This paper discusses parameter estimations of step response from biodiesel transesterification process. The estimates signal generated from impedance measurement from sunflower oil transesterification process. 15 kHz AC signal has used to characterize the capacitance value during the process. The recorded signal then processed using Matlab system identification toolbox. The parametric identification method is selected to develop model structure. The model structure has modelled based on three different structures, ARMAX, BJ and ARX. The algorithm generated from identification toolbox as well as validation test. The validation test including correlation and cross correlation test. ARMAX structure appeared to be best between the others structure.
