  PID Controllers Working, Construction and Tuning Method Before explaining PID Supervisor, let's revise about Control System. There are   kinds of structures; open loop gadget and near loop gadget. An open loop device is likewise known as an out of control machine and close loop machine is called a controlled device. In open loop gadget, the output isn't always managed because this gadget has no comments and in a close loop gadget, the output is controlled with the assist of controller and this machine requires one or extra feedback paths. An open loop device is very simple but not useful in commercial manage programs because this machine is uncontrolled. Close loop machine is complex however most useful for industrial application, due to the fact on this gadget output can be strong at a favored cost, PID is an example of Closed Loop System. Block drawing of this systems is as shown in below .figure-1 A near loop system is also called remarks manipulate device and this kin
