Abstract
The area of robust control, where the performance of a feedback system is designed to be robust to uncertainty in the plant being controlled, has received much attention since the 1980s. System analysis and controller synthesis based on the H-infinity norm has been central to progress in this area. This article outlines how the control law that minimizes the H-infinity norm of the closed-loop system can be derived. Connections to other problems, such as game theory and risk-sensitive control, are discussed and finally appropriate problem formulations to produce “good” controllers using this methodology are outlined.
