中文摘要
      定子电阻的准确估计是改善直接转矩控制低速性能的关键技术. 为了提高定子电阻的在线估计精度和速度, 本文将小波分析、自组织算法和神经网络技术相结合, 提出了一种自组织小波神经网络定子电阻估计器. 该网络继承了小波分析优异的局部特性和神经网络的自学习能力, 具有较高的估计精度. 并采用自组织算法对小波元的数量进行了离线优化, 大大简化了网络结构, 提高了在线估计的实时性.
英文摘要
      Exact estimation of stator resistance is the key technology to improve the low speed performance of direct torque control. To improve the accuracy and speed of on-line stator resistance estimation, a self-organization wavelet neural network estimator is proposed in this paper by combining wavelet analysis, self-organization algorithm and neural network technology together. The proposed network inherits the excellent local performance of wavelet analysis and the self-learning ability of neural network to get high estimation accuracy, and its wavelet number is optimized off-line by using self-organization algorithm to simplify the network structure and improve the on-line estimation speed.
