H-infinity Methods

H-infinity (H∞) methods are advanced control techniques used to design systems that perform reliably despite uncertainties and disturbances. Think of it as a way to optimize a system's robustness by minimizing the worst-case impact of external factors, much like preparing for the most challenging conditions. These methods analyze and shape system behavior to ensure stability and performance, even in unpredictable environments. They are widely used in engineering fields like aerospace, robotics, and process control to create resilient systems that maintain their functionality under varying or uncertain circumstances.
