Exergy-Wise Predictive Control of Building and Automotive Energy Systems

建筑和汽车能源系统占加拿大消费者总能源使用量的57%，同时造成加拿大36%的温室气体(GHG)排放。该计划的目标是开发新的控制方法，以最大限度地减少建筑和汽车能源系统的能源消耗和温室气体排放。该计划的短期目标是为能源系统创建一个统一的建模和控制理论，该理论基于有序的度量“(火用)”，即理论上可以做功的最大可用能量。该程序将通过基于热力学第二定律、火用流量控制和反馈控制稳定性的新理论，为火用智能控制创造一个新的范例。PI的最新结果表明，机械-热力-化学(MTC)能源系统的火用控制提供了显著(7%-36%)节能的机会。在PI结果的基础上，提出的研究方法将包括基本的多物理(火用)破坏建模、(火用)表面成形和热力学流动控制。研究计划将集中于MTC能源系统；该理论将应用于内燃机(ICE)和建筑供暖、通风和空调(HVAC)系统，这些系统占加拿大消费者总能源使用量的46%以上。*长期目标是将该计划的统一建模和控制理论框架扩展到广泛的机械-热力-化学和电气(MTCE)能源系统(例如，混合动力汽车)和互联的MTCE能源系统(例如，建筑物到电网系统)。*该计划将培训11名博士、理学硕士(MSC)和理科学士(BSC)学生，通过使用新颖而强大的火用控制技术，开发独特的技能，将MTC系统的能耗降至最低。从这个项目中获得的知识将通过计划中的行业短期课程传递给相关行业。此外，还将开发新的课程，这些课程将在线提供给公众使用，并向全球研究界推广。*智力价值：控制研究界和热力学研究界之间存在着重大的知识鸿沟，必须填补这一鸿沟，才能实现能源系统的火用智能控制方法。这项研究计划旨在填补这一知识空白。*更广泛的影响：新的火用控制理论将适用于所有机械-热-化学系统。特别是，将该理论应用于该项目中的冰，预计将对开发广泛应用于汽车、发电、石油和天然气、船舶和铁路行业的节能型冰做出重大贡献。第二个直接影响领域包括商业和住宅建筑暖通空调系统的节能，这些系统占加拿大消费者总能源使用量的16%以上。**

Building and automotive energy systems account for 57% of total energy use by consumers in Canada, while causing 36% of Greenhouse Gas (GHG) Emissions in Canada. The goal of this program is to develop new control methods to minimize energy consumption and GHG emissions from building and automotive energy systems. The short term objective of this program is to create a unified modeling and control theory for energy systems based on an ordered metric, “exergy,” i.e., the maximum theoretically available energy that can do work. This program will create a new paradigm for exergy-wise control through a novel theory based on the Second Law of Thermodynamics, Exergy Flow Controls, and Feedback Control Stability. The PI's recent results show exergy-wise control of Mechanical-Thermal-Chemical (MTC) energy systems provides opportunity for significant (7-36%) energy savings. Building upon the PI's results, the proposed research approach will include fundamental multi-physics exergy destruction modeling, exergy surface shaping, and thermodynamic flow control. The research program will center on MTC energy systems; applications of the theory will be demonstrated for internal combustion engines (ICEs) and building heating, ventilation, and air conditioning (HVAC) systems that cause over 46% of total energy use by consumers in Canada.***The long term goal is to extend the unified modeling and control theory framework from this program to include broad Mechanical-Thermal-Chemical & Electrical (MTCE) energy systems (e.g., hybrid electric vehicles) and connected MTCE energy systems (e.g., buildings-to-power grid systems). ******This program will train 11 Doctoral, Master of Science (MSc), and Bachelor of Science (BSc) students for developing unique skills to minimize energy consumption of MTC systems by using novel and powerful techniques of exergy-wise controls. The resulting knowledge from this program will be transferred to the relevant industry through planned industry short courses. In addition, new courses will be developed that will become available on-line for public use and outreach to the global research community.******Intellectual Merit: There is a significant knowledge gap between the controls research community and the thermodynamic research community that must be filled to enable exergy-wise control methods for energy systems. This research program aims to fill this knowledge gap.******Broader Impacts: The new exergy-wise control theory will be applicable to all mechanical-thermal-chemical systems. In particular, the application of the theory to ICEs in this program is anticipated to make a major contribution to the development of fuel-efficient ICEs that are widely used in automotive, power generation, oil & gas, marine, and rail industries. The second direct impact area includes energy saving for commercial & residential buildings HVAC systems that cause over 16% of the total energy use by consumers in Canada. **
