PID stands for Proportional-Integral-Derivative, a control loop feedback mechanism used in engineering.
PID is a control algorithm that calculates an error value as the difference between a desired setpoint and a measured process variable.
Proportional (P) control responds to the current error value.
Integral (I) control accumulates past errors to correct the present error.
Derivative (D) control predicts future errors bas...
