Synergistically Integrated In-Cylinder Condition and Fueling Control for Advanced Multi-Mode Combustion Diesel Engines

该奖项的研究目标是深入研究和开发一种系统控制方法，该方法将缸内状态(ICC)估计、ICC控制和主动燃料控制协同结合，以实现高效和超清洁的先进多模式燃烧柴油发动机平稳而稳健的瞬时运行。为了系统地解决这一现实、能源和环境方面的重要挑战，以下三个主要研究内容将以理论和实验的方式进行：1)非平衡瞬时轨迹成形(NETTS)非线性控制理论的基础研究；2)基于观测器的ICC逐循环估计；3)先进多模式柴油机基于空气路径和基于主动燃料的ICC跟踪和NetTS控制的系统和新颖的集成。系统评估和验证将通过仿真研究和实验进行。这项研究成功完成后，将有可能在柴油发动机上广泛应用先进的燃烧模式，从而大大有利于国家交通部门的能源效率和环境影响(包括二氧化碳)，以及减少国家对外国石油的依赖。研究结果将提高美国汽车业的竞争力。ICC控制方法可推广到其他能量转换系统的热力边界条件控制。Netts非线性控制理论可以提供新的控制技术，这些技术对许多其他瞬变轨迹关键系统具有潜在的实用价值。该项目的研究成果将用于丰富三门本科/研究生/远程课程。此外，本科生将通过这个项目创造研究机会，以吸引学生，特别是那些来自代表不足的群体的学生，参与到研究中来。此外，国际和平研究所将开展K-12和公众宣传活动，并在行业中传播研究成果。

The research objective of this award is to conduct an in-depth investigation and development of a systematic control methodology that synergistically combines in-cylinder condition (ICC) estimation, ICC control, and active fueling control to enable smooth and robust transient operations of advanced multi-mode combustion Diesel engines which are highly-efficient and ultra-clean. To systematically address this real-life, energetically and environmentally important challenge, the following three main research elements will be conducted in a theoretical and experimental fashion: 1) fundamental research on non-equilibrium transient trajectory shaping (NETTS) nonlinear control theory; 2) observer-based ICC cycle-by-cycle estimation; and 3) systematic and novel integration of air-path-based and active-fueling-based ICC tracking and NETTS control for advanced multi-mode combustion Diesel engines. System evaluations and validations will be conducted through simulation studies and experiments. The research, upon successful completion, will have the potentials of enabling widespread applications of advanced combustion modes on Diesel engines, and thus significantly benefiting the national transportation sector's energy efficiency and environmental impacts (including CO2), as well as reducing the nation's dependence on foreign oil. The research findings will enhance the competitiveness of the U.S. automotive industry. The ICC control methodologies can be extended to control of thermodynamic boundary conditions for other energy conversion systems. The NETTS nonlinear control theory can provide new control techniques that are potentially useful for many other transient-trajectory-critical systems. The research results from this project will be used to enrich three undergraduate/graduate/distance courses. Moreover, undergraduate student B.S. Honors Program research opportunities will be generated through this project to attract students, particularly those from underrepresented groups, to engage in the research. In addition, the PI will conduct K-12 and public outreach activities and industrial dissemination of the research findings.
