基于BP网络模拟步进电机细分控制优化控制量的方法

Methods of Simulating the Optimal Control Codes in the Subdivision of Stepping Motor Based on BP Network

用BP网络模拟步进电机细分控制中电机优化控制量与电机角度输出的非线性关系;并对网络结构的确定以及已知实验数据的分析处理作了探讨。对优化控制量模拟的结果表明,BP网络能够实现对这一非线性关系的精确逼近。

A method that simulates the nonlinear function between the optimal control codes and the angle displacements in the subdivision of stepping motor is proposed;and how to determine the structure of BP network and to select the reasonable known data from experiments are also discussed. The result of simulation suggests that BP network can approximate the nonlinear function with enough precision.
