基于零维模型的船用共轨增压柴油机硬件在环仿真模型研究
|
摘要
船用共轨增压柴油机硬件在环仿真模型,要兼顾模型准确度和实时性。平均值模型实时性好,但准确度不高,准维模型准确度高,但不满足实时性要求。本文针对16缸船用共轨增压柴油机,建立基于缸内过程热力学计算的零维实时仿真模型。通过实时仿真试验验证了模型功能、精度和实时性,满足硬件在环仿真要求。
The real time simulation model of common rail and turbocharged marine diesel engine is used on hardware in the loop. The accuracy and real-time of the model should be taken into account. The average value model has good realtime performance, but the accuracy is not high. The accuracy of the quasi-dimensional model is high, but cann't be met the requirement of real time. In the paper, a zero dimension real time simulation model based on the thermodynamic calculation of the 16 cylinders common rail and turbocharged diesel engine is established. Through real time simulation testing, the function, the precision and real-time performance of the model meet the requirement of the hardware in the loop simulation.
