Abstract

This paper provides a paradigm consisting of a closed-loop system identification algorithm in terms of Laguerre orthogonal functions to handle variable transport time delay system. The identification algorithm does not require any special excitation signal. Two-closed-loop transfer functions (time domain and frequency domain) from the set point signal to the control input and output are identified using Laguerre orthogonal functions. A plant model is then computed based on the two-closed-loop transfer functions. We perform the entire design and simulation on a virtual diesel engine developed by Cummins Engine Company.
