What is PID controller explain with diagram?

A PID controller is an instrument used in industrial control applications to regulate temperature, flow, pressure, speed and other process variables. PID (proportional integral derivative) controllers use a control loop feedback mechanism to control process variables and are the most accurate and stable controller.

What 3 values does the PID controller calculate?

A PID controller receives the process variable from sensors and calculates the corrective action to the control variable (output) based on the error (proportional), the sum of all previous errors (integral), and the error rate of change (derivative).

What is PID controller with example?

An everyday example is the cruise control on a car, where ascending a hill would lower speed if constant engine power were applied. The controller's PID algorithm restores the measured speed to the desired speed with minimal delay and overshoot by increasing the power output of the engine in a controlled manner.
