7. Physical Modeling
Reading Assignment
- Chapters 4 and 5 in the book Modeling and Identification of Dynamic Systems (edition 1 or 2)
Learning goals: You should be able to perform dimensional analysis to determine dimensionless variables, and to use the Buckingham's Pi-theorem to deduce expected structure of physical laws. You should know effort and flow variables for the domains of electric systems, mechanical translation and rotation, flow systems, and thermal systems. You should know about the similarities between these different physical domains.
