J4. 2012, 30 (6):  555-561. 
Abstract ( 484 )  

In order to achieve the diagnosis of fault categories of permanent magnet synchronous motor, fault feature is extracted by using wavelet function according to the different frequency band, then normalized date sample as the SOM(Self Organizing Map) network input, the SOM field function is constructed with the wavelet function and the second excited neurons are formed to update weights, so the local optimization of SOM is avoided. The fault data extracted is regarded as the input samples of SOM neural networks in order to train the network, and appropriate neuron index stimulated when a specific fault occurs is obtained. the feasibility has been demonstrated by simulation results.

Abstract ( 542 )  

Task allocation model based on single objective function can not provide more useful information for the fire control decision makers. In order to make up the deficiency, the wastage cost of UCAV (Unmanned Combat Aerial Vehicle) and damage value of target are treated as two optimization objective functions of the task allocation for MultiUCAV cooperatively attacking multiple targets, and a new task allocation model is established. Based on the optimization model, an improved NSGA-II(Nondominated Sorting Genetic Algorithm II) with elitist strategy is adopted for searching the Pareto optimal solutions of the task allocation of cooperative attacking multiple targets for MultiUCAV. The decision makers select the best task allocation scheme according to their preferences. Simulation results demonstrate that the algorithm of task allocation is convergent and effective.
