A Strategy about Hoist Control and Fault Diagnosis Based on Neural Network

In order to exert the potential of mine hoist, a kind of control system is designed by use of integrating fault diagnosis with fault tolerate, according to the property of mine hoist control system. It can auto-monitor, diagnose and tolerant control. It advises that tolerant control can be realized by use of the integrated intelligent sensor tolerant control scheme in the control system of mine hoist. It can assure the mine hoist run stably under the sensor fault and avoid accident. The concrete mode is discussed to realize the whole and the part of the tolerant control system of mine hoist which bases on the fuzzy neural network. The system is simulated and the result proves the system is of characteristic of tolerant control and reliability.
