采用工业以太网的直流电机控制系统

Study on the Control Systems of DC Motor Based on Industrial Ethernet

在原有直流电机控制实验系统的基础上,采用泓格I-8837嵌入式控制器将工业以太网由信息层延伸到控制层和设备层,完成PC机和现场控制设备间的通信.借助以太网实现对直流电机的启动、调速和停止的远程监控,同时应用扩充临界比例法对比例-积分-微分(PID)参数进行工程整定.测试结果表明:系统具有准确、稳定和运行可靠的特点,符合网络实验室的要求.

Based on the control experiment of DC motor,the application of industrial ethernet is expanded from information layer to control layer and equipment layer by using ICP DAS I-8837 embedded controller,and then the communication between PC and the on-site control equipment is achieved.With the ethernet,the operating conditions of DC motor for the start,the speed control and the stop can be remote monitored,and then the PID parameters can be adjusted by applying the extended critical ratio method.The test results show that the proposed system has exact,stable and reliable characteristics,in line with the requirement of network laboratory.
