What is a PID and PLC controller?

A PID (Proportional, Integral, Derivative) controller is a control loop mechanism 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, integral, and derivative terms to minimise the error and stabilise the process. A PLC (Programmable Logic Controller) is an industrial digital computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis. PLCs can run automatic control programs, including but not limited to PID control.
