摘要 为了对电控系统功能、性能测试和验证,建立了基于平均值原理的16V396TE94船用增压柴油机的数学模型,并且基于Tesis DYNAware软件,建立了增压柴油机多控制需求的参数化仿真模型和动力传动系统仿真模型.利用所建立的仿真模型和dSPACE硬件平台构成虚拟柴油机,与接口设备、真实的柴油机电控系统和执行器相连接,组成半物理实时仿真试验平台.利用该平台进行了起动、调速、相继增压控制等功能与性能仿真,并将仿真结果与配机实验值进行了比较,结果吻合度达到90%,并且特性趋势完全一致.结果表明该仿真系统精度高、实时性好,能够满足电控系统功能及性能测试要求. A mathematical model based on the principles of the mean-value model of the 16V396TE94 diesel was created to test the functions,performance and accuracy of the electronic control system.From the mathematical model,Tesis and DYNAware were used to build a parametric model simulating the demands of the diesel engine over a wide range of controller inputs.In addition,a powertrain simulation model was also established.A semiphysical simulation platform for the diesel electronic control system was designed and implemented beginning with the simulation model on the dSPACE platform.This was linked with a physical I/O board,an electronic control system and the real actuator.The semi-physical platform was used to test engine startup,speed regulation,and sequential turbocharger working conditions.When compared with test data,the simulation results were 90% correct,and the characteristics followed a consistent trend.The simulation test platform generates high-precision real-time results.It effectively meets electronic control system functions and performance testing requirements.
