proportional-integral-derivative control

Proportional-Integral-Derivative (PID) control is a control algorithm commonly used in engineering and automation systems to regulate a process or system. It combines three components - Proportional (P), Integral (I), and Derivative (D) - to calculate a control signal based on the error between the desired setpoint and the actual process variable. The proportional component responds directly to the present error, the integral component reacts to the accumulation of past errors, and the derivative component anticipates future changes based on the rate of error change. The PID controller continuously adjusts the control signal to minimize the error and maintain the system as close to the desired setpoint as possible.
