The Use of MATLAB and GT-SUITE in Simulation and Optimization of The Diesel Exhaust After-treatment System

Abstract

In order to get the best value of the diesel engine aftertreatmeng system, the GT-SUITE and SIMULINK are simulated and tested. The car exhaust post-processing system is simulated on the GT-SUITE flatform in this paper.The multi-objective optimization algorithm in MATLAB is used to balance these conflicting factors in gas exhaust, fluid consume and cost. The results of the Pareto frontier optimization are obtained in the end. Parallel computing toolbox is used in the simulation,and the results show that the speed of simulation is increased over 90% and the optimal value can be obtained according to the requirements.
