Students
in this class will learn modeling and analysis techniques applicable to
electrical, mechanical, and chemical systems. This “systems” view,
that focuses on what is common to these different physical systems, has
been responsible for much of the progress in the last several decades in
aeronautics, robotics, and other engineering disciplines where there
are many different technologies working together.

Starting
with algebraic descriptions of individual components (such as
resistors), the class develops tools capable of predicting large-scale
behavior of dynamic systems that evolve over time. Differential
equations are key ingredients, so we will spend significant time
learning how to derive differential equations from component descriptions.
One of the key ideas in this class is that electrical, mechanical, and
chemical systems may seem very different from each other but often have
very similar behavior, allowing us to draw powerful analogies between
them. Case studies from several areas of engineering will be used to
illustrate the modeling techniques, including examples from robotics,
power networks, drug delivery, vehicle suspension, thermal stress, and
flexible electronics. Students will have the option of doing hands on
experiments that demonstrate the utility of the techniques.

**Topics:**

1. What does it mean to model a physical system?

2. Kirchhoff’s laws and resistors, capacitors, and inductors

3. RC circuits and differential equations

4. LRC circuits and systems that oscillate

5. Fick’s law and chemical diffusion

6. Newton’s laws and dampers, springs, and masses

7. Why springs and dampers are like resistors and capacitors

8. Mass and mechanical oscillation

9. Diffusion in electrical and mechanical systems

Learn modeling and analysis techniques for electrical, mechanical, and chemical systems and discover how engineered systems that seem very different are actually very similar.
