摘要
针对BP神经网络存在局部极小值和收敛速度慢等问题,文章提出了一种改进BP神经网络。基于改进的BP神经网络的智能交流电机调速系统机内检测方法可以大大提高故障诊断的精确性,缩短了诊断时间,可对电机提供可靠而有效的保护。
An improved algorithm of BP neural network is introduced in detail to overcome the disadvantages of conventional BP algorithm. The intelligent BIT technique of an AC speed regulating system based on the improved algorithm of BPNN can enhance the accuracy of the fault diagnosis, shorten the time of diagnosis, and provide credible and effective protection for induction motors.
