PID Control stands for Proportional-Integral-Derivative Control, a widely used feedback loop mechanism in industrial control systems. It helps maintain a desired output by adjusting the input based on the difference between the desired setpoint and the actual process variable. The three components—proportional, integral, and derivative—work together to minimize this error. The proportional part responds to the current error, the integral part addresses past errors by accumulating them over time, and the derivative part predicts future errors based on the rate of change. Together, these components enable precise control of systems like temperature, speed, and pressure in various applications.
