基于模糊神经网络的晶闸管三相桥式全控整流电路故障诊断

Diagnostic Method of Three-phase Bridge Circuit of SCR Based on Fuzzy Neural Networks

针对晶闸管三相桥式全控整流电路参数的不确定性和模糊性特点 ,提出了用智能诊断方法———模糊神经网络对其进行诊断 ,解决了参数存在模糊性和不确定性的难题 ,提高了诊断的可靠性 ,实验证明了该方法的有效性。

In accordance with parameters indeterminacy and fuzziness in the three-phase bridge circuit of silicon controller (SCR), an intelligent diagnostic method, namely using the fuzzy neural networks (FNN) is put forward in this paper. Adopting this method, the problem of parameters indeterminacy and fuzziness can be solved and the reliability of diagnosis can be improved as well. The validity of this method has been proved by experiment.
