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的控制方法，该方法协同结合缸内状态（ICC）估计，ICC控制和主动加油控制，以实现高效和超清洁的先进多模式燃烧柴油发动机的平稳和稳健的瞬态操作。为了系统地解决这一现实生活中，能源和环境方面的重要挑战，将以理论和实验的方式进行以下三个主要研究内容：1）非平衡瞬态轨迹成形（NETTS）非线性控制理论的基础研究; 2）基于时间的ICC逐周期估计;以及3）用于先进的多模式燃烧柴油发动机的基于空气路径和基于主动加油的ICC跟踪和NETTS控制的系统的和新颖的集成。系统评估和验证将通过模拟研究和实验进行。这项研究一旦成功完成，将有可能使先进的燃烧模式在柴油发动机上得到广泛应用，从而大大有利于国家运输部门的能源效率和环境影响（包括二氧化碳），并减少国家对外国石油的依赖。研究结果将提高美国汽车行业的竞争力。ICC控制方法可以扩展到其他能量转换系统的热力学边界条件的控制。NETTS非线性控制理论可以提供新的控制技术，是潜在的有用的许多其他瞬态轨迹临界系统。该项目的研究成果将用于充实三门本科/研究生/远程课程。此外，本科生B.S.荣誉计划的研究机会将通过这个项目产生，以吸引学生，特别是那些来自代表性不足的群体，从事研究。 此外，PI还将开展K-12和公众宣传活动，并在工业界传播研究成果。

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.
