    Abstract
  • For the improvement of reliability and safety for coal wharf's automatic transportation system, a fault-tolerant control method was put forward. Fault detection and diagnosis(FDD) was constructed by using radial basis function network(RBFN), the mapping relationship between FDD and control rule reconstruction(CRR) was built by searching fault-tolerant cases, and CRR was realized. Applying result shows that the proposed method obviously improves the safety and reliability of the system, its fault discrimination ratio is more than 97%, fault misdiagnosis ratio is less then 1%, and the validity of the system rises from 90% to 98%.
