Abstract: This paper proposes a rail pressure tracking controller based on a mon rail system. A
摘要:本文提出了一种轨道压力跟踪控制器基于一种新型的共轨系统。一个
mathematical model, based on physical equations, is developed and used for feed forward control design. Rail
数学模型,基于物理方程,开发了用于前馈控制的设计。轨道压力峰值采样机制的目的是清除轨道压力由于燃油喷射扰动。一个增强跟踪微分器的设计得到平滑的跟踪信号,从信号的精确差分信号噪声。双闭环控制策略的目的是分离系统并提高系统的动态性能该系统。实验结果表明,轨压波动在±1MPa稳定条件,而在±3MPa的瞬态工况,验证了所提出的轨压控制的有效性策略strategy.。
pressure peak sampling mechanism is designed to remove the disturbance of rail pressure due to fuel injection. An
enhanced tracking differentiator is designed to get smooth tracking signal and exact differential signal from signal
with noise. Double loop control strategy is designed to decouple the system and to improve dynamic performance
of the system. Experimental results indicate that fluctuation of rail pressure is within ±1MPa in steady condition,
while within ±3MPa in transient condition, which verifies the effectiveness of the proposed rail pressure control
Key words: accumulating distribution fuel injection system (ADFIS), rail pressure control, tracking differentiator
