摘要
通过试验数据建立了描述发动机稳态控制参数与性能关系的数学模型,并利用目标规划方法协调各种性能指标对控制参数要求上的矛盾,最终得出了使发动机稳态性能指标综合最优的控制参数.
The procedure to optimize steady state control parameters when applying Electronic Fuel Injection (EFI) system to an automotive engine is discussed and studied in the paper. On the basis of the experiment, the mathematical model for optimizing the engine steady state control parameters is worked out, which could concisely express the correlation between the performance and the control parameters. Based on this model the multi-objective programming technique is used to determine optimum engine steady state parameters when several performance indexes of engine are taken together to form the objective function. This optimization procedure is effective in all operating conditions and when the demands for each engine performance index are different.
