Aiming at the accurate prediction of APU residual life in civil aviation, Fusion of historical state performance monitoring data, a method of APU residual life prediction based on proportional hazards model (PHM) is proposed. This method first gives a life prediction algorithm based on PHM. Then, based on the historical performance degradation data and historical failure time data, the genetic parameters...
Aiming at the ordering problem of the key spare parts whose life is consistent with Weibull distribution, an optimization method based on residual life prediction is proposed considering both residual life and the lead time. Firstly, the Weibull distribution parameters of the component life are estimated according to the historical data of the airline and the state change information of the part on...
A hybrid predictive control strategy is proposed which can efficiently deal with the speed regulation control of permanent magnet synchronous generator (PMSG) in wind-energy conversion system. A single linear MPC controller is designed with a simpler linearization model. Model predictive controller generates control voltages which are iuput into PWM controller. Thus PMSG can be controlled by three-phase...
This paper introduces the multiple linear regression, stepwise linear regression, neural network method, and improves the neural network. Comprehensive analysis of the current prediction methods, the application principle of a detailed analysis and comparison of the various prediction methods advantages and disadvantages. Put forward to improve short-term load forecasting accuracy is not only attach...
Emergency department (ED) crowding has developed into a risk that severely impacts on the emergency medical service quality and access to health care. With regard to the essential cause of crowding, subjectively, it results from low efficiency of resource collocation or incomprehension of the patient flow rule; objectively, arises from the low patient flow rate. Hence, the prediction of patient flow...
