Is it for closed loop or open loop systems?
Explain more

Must be closed loop (receive feedback via process variable), "P" stands for proportional (gain), "I" stands for Integral (action),and "D" stands for derivative (action). An analogy of closed loop control to regulate the temperature of a vat: you would give the PID controller a set point temp, the controller would compare the set point withe the measured temp. and generate an error signal to correct the difference.

PIDs are use widely in industrial control systems.
Because of the nature of a PID. (Proportional-integral-derivative) controller it is used in a closed loop system.
The controller will need feedback of the process for proper operation.
It can then act on the resultant feedback to correct its initial state.

I'm pretty sure its for a closed loop system, you put in a controller in order to reduce the steady state error (SSE)
