PID Controller
A PID Controller is an advanced electronic control device that continuously calculates an error value as the difference between a desired setpoint and a measured process variable. It applies a correction based on Proportional (P), Integral (I), and Derivative (D) terms, providing precise and stable control of temperature, pressure, speed, flow, and other process parameters. PID Controllers are essential in industrial automation where accuracy, stability, and responsiveness are critical.
