Adaptive control

Definition

Adaptive control is a type of control system that automatically adjusts its parameters in response to changes in the environment or system dynamics. This flexibility allows it to maintain optimal performance despite variations in system behavior, uncertainties, or external disturbances. It's particularly useful in advanced manufacturing processes where conditions can vary frequently and unpredictably.
