通过对共轨电控喷油器特性试验,发现影响喷油特性的因素较多,且因素之间关系复杂,因此,为保证喷油器性能的一致性及弥补静态补偿不足,提出基于自适应模糊控制的逐缸平衡算法,并利用MAT-LAB工具箱进行了仿真分析及C代码自动生成,最后控制算法嵌入到电控系统进行发动机台架试验。结果表明该算法效果明显,且控制鲁棒性较好,本控制算法的提出从软件上弥补了喷油器之间的不一致性,能实现喷油器在一定范围内互换。

Through the experiment on the characteristics of common rail electronically controlled injector, it is found that there are many factors that affect the fuel injection characteristics, and the relationship between the factors is complex. Therefore, in order to ensure the injector performance consistency and make up for the lack of static compensation, Fuzzy control by cylinder balancing algorithm, and the use of MAT-LAB toolbox for simulation analysis and automatic generation of C code, the final control algorithm embedded in the electronic control system engine bench test. The results show that the algorithm has obvious effect and good control robustness. The proposed control algorithm makes up for the inconsistencies between injectors from the software and can achieve the interchangeability of injectors in a certain range.
