具有最佳一致逼近特性

同时解决了D-S证据理论确定基本信任分配函数的困难和因输入参数改变影响信任分配函数构建的问题。仿真结果表明:该方法可以对木材干燥过程中传感器工作状态进行有效诊断。

Abstract

To determine the effective working state of sensors

a data fusion method based on D-S theory and CMAC neural networks is presented.D-S theory using the redundancy and complementary information of sensor can eliminate the uncertainty in detecting and diagnosis faults.The evidence of sensor state is obtained through a high modularity of the sensor state recognizer network with modularized CMAC

so the advantage of neural net is promoted and the bug of its unusable for change of input parameter is resolved.The simulation results show that the method can determine effective working-state of sensor during wood drying process.
