基于RBF神经网络的无刷直流电机的控制研究

摘要无刷直流电动机是将传感器技术、电力电子技术与传统电机技术相结合,其内部结构采用的是电子换向器。由于其效率高，寿命长，噪声低，可以避免因机械换向器引起的电刷磨损、频繁维修、电磁干扰等优点，因此被广泛应用在国防、办公自动化及工业控制中。随着无刷直流电动机理论分析和设计的日趋成熟，针对其控制方法的研究引起了各国专家学者的重视。

Brushless DC Motor Based on RBF Neural Network Control Research

Abstract Brushless DC motor is a sensor technology, power electronics technology and conventional motor technology, its internal structure is used in electronic commutator。Due to its high efficiency, long life, low noise, the advantages can be avoided due to mechanical commutator brush wear caused by frequent maintenance, electromagnetic interference, it is widely used in national defense, office automation and industrial control。With the theoretical analysis and design of the brushless DC motor is becoming more and more mature, the research on the control method of the brushless DC motor has attracted the attention of experts and scholars in various countries。

The traditional PID control system in a simple univariate linear control system able to reach the target for the control of complex systems is difficult to achieve the desired results。 In this paper, the traditional PID control problems, and its combination with the RBF neural network, the design of RBF neural network based on the PID controller, and the use of MATLAB software for simulation。

The research of this paper shows that the PID controller combined with RBF neural network technology can better meet the control requirements of complex nonlinear system, and has a high superiority compared with the traditional PID controller。

This paper has 14 figures and 32 references。
