基于CAN总线的多无刷直流电机控制研究
Research on Control System of Multi-Brushless DC Motors Based on CAN
摘要
Abstract
In order to realize the long-distance independent control of multi-BLDCM, reduce the number of cable, and improve the reliability of communication, a dual-redundancy distributed control network based on CAN is designed and accomplished. A time-triggered schedule suitable for multi-motor control is also presented to reduce the message transmission delay. Regarding the problem that CAN in the BLDCM control system is susceptible to interference and high error rate in communication, the analysis of the causes of interference is given and some anti-interference measures as common grounding, isolation and filtering from the interface circuit design are put forward. A redundant method of CAN is also researched. The application shows that the multi-BLDCM distributed system has good real-time performance, high communication stability and reliable performance of the redundant switching.关键词
