To propose a new method for controlling the overhead crane systems based on the theory of fuzzy logic with a reduced number of rules than has appeared before in the literature. The proposed fuzzy logic controller (FLC) can be implemented to move the overhead crane along a desired path while ensuring that the payload is swing free at the end of the motion.
In this study, a FLC that includes two rule bases, one for displacement control, the other for swing control, was designed and successfully implemented to move the overhead crane along a desired path while ensuring that the payload is swing free at the end of the motion.
Control simulation results demonstrate that by using the proposed FLC, the overhead traveling crane smoothly moves to the destination in short time with small swing angle and almost no overshoot.
This paper offers practical help to whom are working in controlling the transporting the payloads to the required position as fast and as accurately as possible without collision with other equipments. The proposed FLC can be implemented to move the overhead crane along a desired path while ensuring that the payload is swing free at the end of the motion.
