Feedback control is a powerful approach to obtaining systems that are stable and that meet performance specifications, despite system disturbances and model uncertainties. To under- stand the fundamentals of feedback design, we will study system interconnections and some associated notions such as well-posedness and external stability. Unless otherwise noted, our standing assumption for the rest of the course - and a natural assumption in the control setting - will be that all our models for physical systems have outputs that depend causally on their inputs.
