Typical industrial machines are complex and multi-domain dynamic systems. No single "best" approach exists for their design. Building on the existing knowledge, and the past research and experience in machinery development of the applicant and his trainees, the proposed research will make significant original contributions in the development of systematic procedures for the design of automated industrial machinery. Emphasizing the design optimization of multi-domain engineering systems, the developed methodologies will particularly target performance improvements with respect to their production, operation, and control performance. The research outcomes will be implemented in a prototype industrial machine in the applicant's laboratory and rigorously evaluated for further refinement and transfer to Canadian industry. The following research issues will be investigated: 1. Traditional procedures for machinery design are hierarchically separated into topological design and parametric design. Extending this concept, a mechatronic design quotient (MDQ) will be "structured" into a multi-layered hierarchy and methodologies will be developed for its optimization. 2. Dynamic models can significantly benefit the design process and control performance. The linear-graph (LG) approach will be enhanced for this purpose, models for this purpose, particularly as LG provides a direct correspondence to the physical component topology of the system. New basic elements that can benefit "modeling for design and control" will be explored and developed, including a mechanical element analogous to the "memoristor," a refined and general representation of an inertia element, a thermal element analogous to the "inductor," and various nonlinear, distributed-parameter and vector elements. Strategies for model-based "intelligent supervision" of design optimization will be developed. 3. Improved design can reduce the control burden in an automated industrial machine. In this context, "design for control performance" will be explored and integrated into the overall design methodology.

典型的工业机械是复杂的、多领域的动态系统。他们的设计并不存在单一的“最佳”方法。基于申请者及其受训人员在机械开发方面的现有知识、过去的研究和经验，拟议的研究将在开发自动化工业机械设计的系统程序方面做出重大的原创性贡献。强调多领域工程系统的设计优化，所开发的方法将特别着眼于在生产、运营和控制性能方面的性能改进。研究成果将在申请者实验室的原型工业机器中实施，并进行严格评估，以便进一步完善并转移到加拿大工业。将调查以下研究问题： 1.将传统的机械设计过程层次化地划分为拓扑设计和参数设计。扩展这一概念，机电一体化设计商(MDQ)将被“组织”成一个多层的层次结构，并将为其优化开发方法学。 2.动态模型可以显著提高系统的设计效率和控制性能。为此目的，将增强线性图(LG)方法，为此目的建立模型，特别是当LG提供与系统的物理组件拓扑的直接对应时。将探索和开发有利于“为设计和控制而建模”的新的基本元件，包括类似于“存储器”的机械元件、对惯性元件的精细而通用的表示、类似于“感应器”的热元件以及各种非线性、分布参数和矢量元件。将制定基于模型的设计优化“智能监督”策略。 3.改进设计可以减轻自动化工业机械的控制负担。在此背景下，将探索“为控制性能而设计”，并将其纳入总体设计方法。
