Course description
This is an introductory course to control and optimization of systems driven by partial differential equations (PDEs). The first part of the class will focus on fundamental techniques to solve these equations both analytically (when possible), and numerically. This part of the course will be accessible to students with exposure to control and no (or very little) exposure to partial differential equations. The techniques presented in class will include separation of variables, spectral decomposition, selfsimilar solutions, characteristics, complex embedding. The second part of the class will address stability, control and optimization of these PDEs. It will be accessible to students without background in control. Stability will be investigated using spectral analysis. Adjointbased optimization, HamiltonJacobi and differential flatness techniques will be applied for open loop trajectory design. Lyapunov techniques will be devised for stabilization and control.
The class will put emphasis on networks. Applications (in particular course projects) will include networks of one dimensional systems: water distribution channels, electromagnetic waves in transmission cables, towed cable systems for marine oil exploration, highway systems, oil drilling, mine ventilation networks, blood circulation in vessels. Examples in higher dimensions will include 2D or 3D fluid mechanics, in particular propagation of contaminants in water.
Here is a list of partial differential equations and corresponding applications that will be covered in class:
 The wave equation
 The EulerBernoulli beam equation (materials)
 The heat equation (thermosciences)
 The LWR equation for highway traffic (transportation)
 The SaintVenant equations, shallow water equations, Hayami'e equation (hydraulics)
 The membrane equation (mechanical engineering, MEMS)
 The Telegraph equation (communication)
 Maxwell’s equations (electromagnetism)
 Vibrating string (acoustics)
 Vorticity equation (aerodynamics)
 Euler’s equations (fluid mechanics)
An expanded description of the class is available here.

Projects
For the project, you will be expected to conduct significant work on one of the following topics, or a topic of your choice related to the material covered in class:
 Modeling systems with PDEs for control purposes
 Algorithm design for control and/or optimization of PDE driven systems
 Simulation tools for control of PDE driven systems
 Hardware implementation of control and/or optimization algorithms on a PDE driven system
You will first review the literature on the subject you have chosen. If you choose your own research topic, you will be responsible for finding the proper set of articles relevant for your problem. If you choose one suggested project, some references will be provided to you as a basis for further reading. Depending on your topic, you will balance your time between algorithm design, simulation, and/or hardware implementation. In the first weeks of the project, you will be expected to set up clear goals with the instructor, and a plan to achieve these goals. You will meet with the instructor several time to assess the progress made on the project. You will give a short presentation of your project to the class at the end of the semester.
Reporting
You will be expected to write a report, to summarize your work. We suggest that you use these LaTeX files to write up your report, but you are free to use any editing software you like. Remember that your report should be written in a way which is understandable for someone who does not have exposure to the field. Number tables and figures sequentially and refer to them in the text of the results section. Be sure to label all plot axes and tables and show units of measure. For calculated quantities, report the appropriate number of significant figures. Here is a rough outline of what a good technical report would look like:
 Introduction: objectives of your project, background and motivation.
 Literature review: describe the state of the art in the field; include all proper references, explain where your project fits.
 Problem investigated. Describe the physical system you are modeling, eventually describe the derivation of the model. Pose the problem of controlling the system.
 Control. If you are deriving your own control or optimization algorithm, include all derivations. If the derivations are too long, put them in the appendix, in order to have a clear flow in this section. Summarize your theoretical contributions.
 Simulation. If you are designing a simulation tool for control or optimization purposes, describe which algorithms you have used, and how they address your problem. Describe the software implementation, and the validation of the software (for example on model problems).
 Hardware implementation. If you are implementing control algorithms on an experimental testbed, describe which algorithms you have used, and how they address your problem. Describe the hardware implementation.
 Results: present the results of your experiments in tabular and/or graphical form, but include text that organizes and describes the results to guide the reader through them.
 Discussion: discuss the results, compare with theory, comment on the significance of the results, discuss reasons for disagreement, and suggest how the measurements and the experiment could be improved.
 Summarize the main results and findings of the experiment. Nothing new here; just provide a brief restatement and summary of what is already presented in previous sections.
 Bibliography: list all references used in the text.
 Appendix: include derivations, raw data, calculations, and spreadsheets if appropriate.
