Internal combustion engines, cement kiln combustors are examples of fluid/combustion systems that could see improved performance if suitable control were implemented. This improved performance might be manifested in lower use of energy and/or the ability to operate reliably under changing conditions resulting in a more uniform product. Control strategies that generally apply to fluid/combustion systems remain elusive which necessitates custom solutions for each system which is both time and cost intensive. To make progress on finding control strategies to improve fluid combustion systems, specific examples of internal combustion engines and fundamental fluid flows have been chosen. Control is being used to obtain Homogeneous Charge Compression Ignition (HCCI), an innovative internal combustion engine technology that has higher efficiency, is able to burn a variety of fuels, and has lower exhaust pollutants. Putting this engine in your car would translate into: lower fuel usage and thus lower greenhouse gas emissions, the flexibility to burn biofuels, and the potential for improvement of air quality in large urban centers. Completely variable valve timing, in the form of solenoid intake and exhaust valves allow the potential of HCCI combustion to be realized. The motion control for soft landing of these valves is a mechatronics problem, and whose methodology of nonlinear and adaptive control can be applied to many areas including robotics, process control etc. Fundamental flow control systems are also studied as a basis for controlling more complex and industrially relevant flows. Developing control strategies of a model of a cement kiln combustor should allow more efficient use of the fuel burned on the real system. People trained in the areas of control, fluid mechanics, and internal combustion engines, are needed by industry and government. These highly trained people have the potential to drive new technology creating jobs and keeping our economy competitive.

内燃机、水泥窑燃烧器是流体/燃烧系统的例子，如果实施适当的控制，可以看到性能的改善。这种改进的性能可能表现在较低的能量使用和/或在变化的条件下可靠地操作的能力，从而产生更均匀的产品。通常应用于流体/燃烧系统的控制策略仍然难以捉摸，这需要针对每个系统的定制解决方案，这是时间和成本密集型的。为了在寻找改进流体燃烧系统的控制策略方面取得进展，已经选择了内燃机和基本流体流动的具体示例。 控制被用于获得均质充量压缩点火（HCCI），这是一种创新的内燃机技术，具有更高的效率，能够燃烧各种燃料，并且具有更低的排气污染物。将这种发动机安装在汽车上将意味着：更低的燃料使用量，从而减少温室气体排放，燃烧生物燃料的灵活性，以及改善大城市中心空气质量的潜力。电磁进气门和排气门形式的完全可变气门正时允许实现HCCI燃烧的潜力。阀门软着陆运动控制是一个机电一体化问题，其非线性自适应控制方法可应用于机器人、过程控制等领域。 基本的流量控制系统也被研究作为控制更复杂和工业相关流量的基础。开发水泥窑燃烧器模型的控制策略应允许更有效地利用在真实的系统上燃烧的燃料。 工业和政府需要在控制、流体力学和内燃机领域受过训练的人。这些训练有素的人有潜力推动新技术，创造就业机会，保持我们的经济竞争力。
