Calibration and Validation of a Mean Value Model for Turbocharged Diesel Engine

Blog Article

In order to meet the high requirements of the control strategies for an effective and accuracy control-oriented model, a mean value model for a turbocharged Hose Clamp Pliers diesel engine has been developed on the Matlab/Simulink.And then the error sources leading to the simulation inaccuracy have been analyzed comprehensively and two sets of experiments for model calibration and validation have been designed.Then a model calibration process and a model validation process have been proposed, with which the developed model is well calibrated and validated against the two sets of experimental data.

Especially, for the compressor Big Sister Big Brother model calibration, an improved Jensen and Kristense method has been introduced to interpolate and extend the compressor maps.And turbine efficiency observer is designed for the rectification of turbine maps.At last, the calibration and validation process and improved methods and observer for turbocharger are verified and evaluated.
