| 摘 要： | 电动执行器作为控制系统的终端部件比较容易出现故障，从而对控制性能产生直接的影响。D—S证据理论在处理数据的冲突性和数据的敏感性方面存在一定的缺点，针对这一缺点将其进行改进，将改进后的理论应用于电动执行器的故障诊断，通过诊断数据的比较结果可以看出改进后的证据理论在处理冲突性数据方面是可以得到更为合理的结果的。

| Abstract: | As the terminal components of the control system,the electric actuator is easier to produce faults,which result in the direct effect on the control performance. There is some weakness on the treatment of the data' s conflicting and sensitivity using the D-S evidence theory,and this paper improved on the weakness,the improved theory is applied on the fault diagnosis of the electric actuator,which can get the more reasonable result on the treat with the conflicting and sensitivity data from the diagnosis resu... |
