Modeling of a Compressor's Performance Map by Fitting Function Methodology

Abstract:

To build a precise compressor model is a critical issue in the modeling and simulation of a turbocharged diesel engine. This paper proposes an exponential function for compressor flow model and a polynomial function for efficiency model. A case study of a compressor map for TCA88 turbocharger is implemented to verify the proposed model. Fitting results show that the compressor model performs in accordance with the manufacture compressor map. The compressor model can be applied to mean value models of turbocharged engines for non-linear control and state estimation.
