A new structure design for ball and beam system using fuzzy PID controller with reference model / Nur Sakinah Abdul Aziz

Ball and beam position control system is one of the most popular laboratory equipment used to study about nonlinear dynamics and open-loop unstable control system. The unstable behaviour such as time taken for ball to stable on the beam can be observed where the ball will move continuously on a beam...
