Engineering system co-design with limited plant redesign

摘要: Rather than designing engineering systems from the ground up, engineers often redesign strategic portions of existing to accommodate emerging needs. In mechatronic systems, typically seek meet requirements a new application via control only, but this is insufficient and physical system (plant) design changes must be explored. Here, an integrated approach presented for involving partial plant that avoids costly complete redesign. Candidate modifications are identified using sensitivity analysis, then optimization problem solved minimizes cost while satisfying requirements. This formal methodology Plant-Limited Co-Design (PLCD) demonstrated robotic manipulator problem. The PLCD result costs significantly less full redesign, parametric studies illustrate tradeoff between performance. It shown propos...
