H-infinity control is a robust control strategy that aims to design controllers that minimize the worst-case gain from disturbances to the output of a system. This approach is particularly valuable in control system design, as it helps ensure system performance and stability in the presence of uncertainties and external disturbances. By focusing on the H-infinity norm, this method provides a way to quantify the level of disturbance rejection and ensures that the system remains resilient under various conditions.
congrats on reading the definition of h-infinity control. now let's actually learn it.
