What is a PID controller and how can it to applied to our
everyday life?
Answer Posted / ajith294
At first you should understand what is the controller.
A controller is the device in a closed loop, that compares the measured valve (actual valve) with the desired valve and calculate the out put manipulated variable. Then The time (T) responds is determined by P,I,D
P: manipulated variable our put is proportional to the system deviation. that means variable only present if there is any system deviation.
I: manipulated variable is continues to increase, the system deviation decreases. this process continuous until system deviation is zero.
D: Differential compound evaluate the speed of change of the system deviation.
so if using the PID controls, we can control the flow to our desired valve at a very short time.
Best Regards
