Perfect tracking control and fault diagnosis for RMG

RMG (Rail-mounted Gantry) plays a more and more important role in modern harbor. Gnawing rail problem limits its further quick development. For the first time, the article apply perfect tracking control (PTC)[1] put forward by Hiroshi Fujimoto et al. to the control of RMG to reduce gnawing rail problem. We also put forward an intelligent fault diagnosis system aimed for gnawing rail problem. Basing on the “different reasons have different phenomena” principle, the fault diagnosis system can locate the reasons by making use of multisensor information fusion and fault diagnosis logic deduction system. The combination of both methods can prevent and decrease gnawing phenomenon to a great extent. The system not only can minish gnawing rail phenomenon, diagnose causes of gnawing rail and give an corresponding alarm, but also has the capacity of preventing gnawing rail phenomenon beforehand. And the method has a wide application foreground to other rail-mounted vehicles too.
