Closed-Loop Control System
A control system in which the system output is fed back to the controller through sensors, and the controller adjusts its input accordingly, forming a loop. Unlike open-loop systems, the state distribution in a closed-loop system is determined jointly by the controller policy and the plant dynamics. It is a foundational concept in control theory, widely applied in robotics, autonomous driving, and industrial control.
Timeline (last 90 days)
When a neural network trained offline is deployed to a closed-loop control system, its actions change the system's state distribution, causing the data distribution at actual runtime to deviate from the offline data distribution at training time, that is, distribution shift.
A closed-loop control system refers to feeding the system output back to the controller via sensors, upon which the controller adjusts the input, forming a cycle of sensing—decision-making—execution—re-sensing.
