电机嵌入式CAN总线控制系统设计

Research on Embedded CAN Bus Control for Motor

传统的电机驱动架构多采用集中控制模式,即控制器与电机驱动器采用一对一的信号线以脉冲信号形式直接互联控制模式~[1],此种控制模式在可靠性方面存在不足,当不同电机之间需要协同作业时,更是难以达到实时性的要求。基于此,本文提出了一种电机嵌入式CAN总线智能控制系统,采用CAN总线可以同时与多个节点进行通讯,且各个节点之间互不影响的情况的特点,与传统的电机控制相比,具有可靠性高、灵活性强、实时性好、控制精度高的特点。

The traditional motor-driven architecture uses centralized uses centralized control mode.The controller and the driver adopt the one-to-one signal line in the form of pulse direct connection control mode.The control mode is somewhat inadequate in the real and reliability inspect,especially between the different motor control module.This paper presents a motor embedded CAN bus intelligent control system,by using can bus to communicate with multiple nodes at the same time,and the characteristics of each node without influence,compared with the traditional motor control,including high reliability,flexibility,real-time good features.For the future aviation field,the field of ships high precision,fast mobile control,has a certain practical value.
