The result of the experiment is shown the Non PID controller system , the P controller system , the PI controller system and the I controller system are not close to the design value but the PID controller system and PD controller system are close to the design value.
The study of PID controller system found that the PD controller system is the fastest system to closing to the design value.
The tendency of the rise time , the settling time and the overshoot will increase direct variation to K.
