单体泵柴油机基于模型的标定优化研究

Optimizing Calibration Study on the Pump Diesel Engine

利用MATLAB软件提供的模型标定（Model-Based Calibration,MBC）工具箱,对某单体泵柴油机试验进行电控系统参数经济性优化标定,详细说明了基于模型标定方法的基本流程,包括试验设计、模型建立和优化标定等。理论和实践结果表明这种方法有效地降低了试验成本,同时缩短了标定周期,并能够得出合理的最优电控控制参数组合。

The model-based calibration toolbox in Matlab software was used to optimize the fuel economy of pump diesel engine. The whole process of model-based method,including testing,modeling,optimization and etc. is introduced. Analytical and experimental results show that the method can obviously reduce the workloads with an identical accuracy level compared with the conventional methods. Development period is shortened and it achieves the reasonable controlling parameter units.
