基于直流力矩电机的位置控制伺服系统研究

Servo system of stable speed control based on direct current torque motor

为了满足工控平台能快速,稳定控制负载位置的需求,设计了一种基于直流力矩电机的位置控制伺服系统.该系统的硬件部分主要由ARINC429通信卡、高性能DSP控制器、光电编码器、直流力矩电机和数据采集卡组成.首先通过ARINC429通信卡发送根据协议产生的通信指令,用来控制电机的转速和位置.再利用光电编码器和数据采集卡来反馈位置信息,最后在上位机上进行监控.软件部分采用labview进行编写,上下位机通过自定义的通讯协议进行数据通信,上位机发送命令到下位机,下位机接收命令并处理后将结果反馈给上位机,从而实现对下位机平台的控制.通过随动系统项目的应用测试,证明该系统功能稳定,能够满足实际项目的基本需求.

To make the industrial platform control the motor position fast and stably, a servo system of steady speed control based on direct current torque motor was designed. The hardware part of the system consists of a high-performance DSP controller ARINC429 communication cards, photoelectric encoder, direct current motors and data acquisition cards. ARINC429 communication cards were utilized to communicate the data.The optical encoder and data acquisition cards were used to collect and feedback position information, and the position information was lastly monitored by the upper computer. The software part was written by the language of labview. A self-define communications protocol was applied to serial communication for the upper platform and the lower platform. The upper computer sent commands to the lower computer, and the lower computer received commands and gave feedback to the upper computer after processing, enabling control of the lower platform. The application test results show that the system is reliable and can meet the basic needs of the actual project.
