What is this PID and why is it much talked? Well, PID means proportional–integral–derivative and it is a control feedback method applied in different control systems, its main task is to minimize the error of whatever you are about to control. It is superior quality error control feedback mechanism and the general industry standard. Speaking simple it takes in the inputs calculates the deviation from the intended behaviour and accordingly adjusts the outputs so that the deviation from the desired behaviour is minimized thus getting the highest possible accuracy.
