高压油管压力控制是维持内燃机燃油效率的重要途径.为了提高控制精度,本文对燃油密度、喷油器针阀运动、凸轮转动等做精确的函数拟合,进一步揭示了它们的变化规律.接着,讨论了利用质量守恒定律建立的微分方程组,根据不同控制要求给出了目标函数.最后,基于python编程,计算了使高压油管内压力保持稳定的最优参数.
The Differential Model and Solutions for the Pressure Control Problem of the High-pressure Oil Tubing
The pressure control of the high-pressure oil tubing is an important way to maintain the fuel efficiency of combustion engines.In order to improve the control accuracy,we accurately fits functions such as fuel density,injector needle valve movement,and cam rotation,further revealing their changing laws.Next,the differential equations established by the law of conservation of mass are discussed,and the objective functions are given according to different control requirements.Finally,based on Python programming,the op-timal parameters for maintaining stable internal pressure in high-pressure oil tubing are calculated.
