AEM8453: Model Reduction and Approximation of Dynamical Systems

In this course, we will study analytical and data-driven methods for model reduction and approximation ofdynamical systems. The focus will be on learning the relevant mathematics and tools for obtaining “lean”low-dimensional representations of dynamical systems, which can be used to facilitate analysis and design.Roughly half of the course will be devoted to the problem of model reduction: i.e., given a mathematicaldescription of a system, reduce the number of degrees of freedom required to faithfully represent that system.The other half of the course will be devoted to data-driven approximation of dynamical systems: i.e., givenempirical data generated by a dynamical system, determine a mathematical representation for the underlyingsystem dynamics. Although these two general problems are distinct, they are closely related and will bestudied in parallel throughout the term.
