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域动态系统。对于它们的设计，不存在单一的“最佳”方法。根据申请人及其学员的现有知识，以及过去在机械开发方面的研究和经验，建议的研究将对自动化工业机械设计的系统程序的发展作出重大的原创性贡献。强调多领域工程系统的设计优化，开发的方法将特别针对生产、操作和控制性能方面的性能改进。研究成果将在申请人实验室的原型工业机器中实施，并经过严格评估，以进一步改进和转移到加拿大工业。将调查以下研究问题：
