State prediction algorithm for electromechanical equipment based on information fusion

摘要

A method of state prediction based on information fusion is proposed for the difference of test mode, mixed quantitative and qualitative information of electromechanical equipment state prediction. This method fused decision level information of electromechanical equipments by using DS evidence theory. Simulation results show that it is feasible and effective that information fusion technology is applied on the state prediction for mechanical and electrical equipment. Information for decision-making integrated repeatedly by different forecasting methods, can greatly reduce the blindness of judgment and improve the accuracy of state prediction.
