Design of a fuzzy controller: some experience

This paper describes the design and implementation of the fuzzy controller for an overhead crane model. A model used in this project was a laboratory model of the gantry cranes commonly seen in dockyards and factories. The fuzzy controller is used for suppressing load swing while positioning the trolley of an overhead crane. Simulation and experimental results are included to verify the validity of the controller developed. Further discussions on the utilisation of this laboratory model is provided.
