| Abstract:A dynamic model of centrifugal compressor was established based on the law of thermodynamic. The model could use only the basic structural parameters of the compressor without using the experimental data map. The compressor and turbine models consisting a turbocharger dynamic model were used in a joint matching simulation with the diesel engine model. Results show that the model enlarges the working range of compressor model and effectively improves the dynamic performance of diesel model especially at lower revolution and lower load. The model has fast calculation speed and excellent real time performance, which can be used in engine performance optimization, control system development, etc. |
