【Abstract】 In order to reduce the development time and cost of engine control systems, combination simulation environment based on MATLAB/Simulink and GT-power was built and a co-simulation model of a sequential turbocharging diesel engine was established. The simulation results were compared with experiments, and it is proved that the co-simulation model is suitable for development of seuqential turbocharging control system. Switch of sequential turbocharging system was simulated, and the significance of this simulation platform was analyzed to the design of engine control system.更多还原
