Closed Loop Identification Using Laguerre Orthogonal Functions for a Virtual Diesel Engine

摘要：

This paper provides a paradigm consists 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 frequence domain) from the setpoint 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.
