Integral Control

Integral control is a method used in systems to maintain a desired level or output by continuously accounting for past errors. It works by summing the difference between the desired and actual values over time and then adjusting the system's input accordingly. This helps eliminate steady-state errors, ensuring the system stabilizes at the target value. For example, in a temperature control system, integral control gradually increases or decreases heating to precisely match a set temperature, even if conditions change. It complements other control methods by focusing on correcting accumulated deviations for accurate, stable performance.
