A Proposal of Fuzzy Control System for Trailers Driven by Multiple Motors in Side Slipway to Launch and Pull Out Ships

摘要

This paper describes on a control system of multiple-motor system for a side slipway ship pulling out system using fuzzy logic control. The main control system is responsible for synchronized motion of trailers and fuzzy control system is used as a key control system for compensating a velocity error, rotational error and distance error caused by the unsynchronized motion of the trailers. A simulation system is used to evaluate the performance of the control system and five different types of common errors are used for testing the outputs of the control system.
