摘要
研究并实现了基于DSP和CPLD的无刷直流电动机(BLDCM)全数字伺服控制器与其上位机控制软件之间的RS-485串口通信。电动机按上位机给定指令作动;上位机软件采用虚拟仪器Lab VIEW编写,界面友好,具有发送控制指令,将位移、电流等反馈数据显示、保存和制表的功能。实验结果证明系统具有良好的伺服性和实时可监测性。
Research and implementation on RS-485 serial communication between digital servo controller based on DSP and CPLD of BLDCM and PC control software. Motor moves according to Host software’s given actuation instructions; Host software using the virtual instrument LabVIEW, sends control instructions, displays, saves and tabulates feedback data such as displacement and current. The test results prove that the system has a good servo and real time monitoring performance.
