Adaptive control systems

Definition

Adaptive control systems are control systems that adjust their parameters automatically in response to changes in the system dynamics or environment. This capability allows them to maintain optimal performance even in the presence of uncertainties, making them particularly valuable in applications where conditions are variable or unpredictable. Such systems are crucial in fields like robotics and automation, where adaptability is essential for effective operation.
