What is the full form of a PID controller?

Question

Accepted Answer

Proportional Integral Derivative controller

PID controller is a control loop feedback mechanism used in systems to control the output based on the error between the desired setpoint and the actual process value.
The three terms in PID stand for Proportional, Integral, and Derivative. Proportional term responds to the current error, Integral term integrates the error over time, and Derivative term predicts future error trends.
Example: In a temperature control system, a PID controller can adjust the heating or cooling output based on the difference between the desired temperature and the actual temperature.
PID controllers are widely used in industries such as manufacturing, robotics, and automation for precise control of processes.
