Abstract :
System identification is an experimental approach to determine the transfer function or equivalent mathematical description for the dynamic of a system component by using a suitable input Signal.A pseudorandom binary sequence (pRBS) signal of 5 different maximum lengths sequence of 15,31,63,127, and 255 has been used as an input signal to determine the open-loop and closed-loop model of a hot air blower system. The autocorrelation of the input Signaland cross-correlation between the input and output Signalis performed using the Dynamic Signal Analyzer (DSA) and MATLAB software. From the correlograms of cross-correlation and autocorrelation, the transfer function model can be determined.
