Predictive control

Definition

Predictive control is a control strategy that utilizes mathematical models to predict future behavior of a system, allowing for proactive adjustments to be made in real-time. This approach enables systems to anticipate changes and optimize performance, often used in environments where conditions can vary significantly. By leveraging predictions, predictive control can enhance the precision and stability of systems like adaptive optics for lasers, improving beam quality and focusing capabilities.
