Adaptive control strategies

Definition

Adaptive control strategies refer to techniques that allow a control system to adjust its parameters automatically in response to changes in the environment or system dynamics. This approach is crucial for robotic systems that operate in uncertain or varying conditions, enabling them to maintain optimal performance by continuously adapting to new information about their workspace and potential singularities.
