I've been trying to search for some sort of list of top schools for graduate study in control theory. While there are rankings available for electrical engineering in general, I'm having a hard time finding rankings for specific specializations. So far I've heard Carnegie Mellon, Stanford, MIT, Caltech, Georgia Tech, Purdue, Michigan. Can anyone with more experience than myself (graduate students in controls possibly?) give me their opinion on schools I may have missed, or if there are any schools that do not belong in my list? By the way, I am a senior undergraduate in electrical engineering.
