This page hosts information on Alejandro López's talk "What is... control theory?" at the "What is …?" seminar. This talk will help you better understand the talk by Fatiha Alabau-Boussouira.
I will give a short survey on control theory, some of the many ways in which it can be approached and its applications in the real world. After this the talk will focus on Pyragas control, a special technique used to modify the stability of particular elements within a dynamical system.
