Which term refers to the adjustment made in a controller to counteract changes in load or set point?

The term that refers to the adjustment made in a controller to counteract changes in load or set point is feedback control. Feedback control involves continuously monitoring the output of a system and comparing it to the desired set point. When any deviation occurs due to changes in load or disturbances, the controller automatically makes adjustments to bring the output back to the set point.

This process is fundamental in maintaining the desired operation of systems by responding to fluctuations in real-time, allowing for improved stability and performance. Feedback control is widely used in various industrial applications where maintaining a specific condition is critical, such as temperature regulation, pressure control, and flow management.

In contrast, feedforward control anticipates changes and acts preemptively, while adaptive control adjusts its parameters in response to changing conditions. Nonlinear control deals with systems that exhibit nonlinear behavior, which may not directly address the typical load or set point changes like feedback control does.
