摘要
针对汽车涂装生产过程烘房温度易受干扰等问题,研究了自抗扰控制(ADRC)算法基本工作原理和控制过程,基于西门子博途PLC平台设计实现了ADRC控制程序,利用Simulink平台搭建烘房动态模型,通过OPC技术与PLC建立通讯连接,实现了汽车烘房温度控制系统的实时仿真,采集烘房温度的响应曲线,并与传统PID控制的温度响应曲线进行对比分析。结果表明,ADRC在动态响应速度和控制效果上均优于传统PID控制,对解决复杂的烘房温度控制问题具有一定的应用价值。
To address the problem of temperature in the automobile drying room being easily affected by disturbances during the painting process,this study investigates the fundamental working principles and control process of the Active Disturbance Rejection Control(ADRC)algorithm.An ADRC control program was designed and implemented based on the Siemens TIA Portal PLC platform.A dynamic model of the drying room was built using the Simulink platform,and real-time communication with the PLC was established via OPC technology.This enabled real-time simulation of the automobile drying room temperature control system.The temperature response curve of the drying room was collected and compared with that of traditional PID control.The results show that ADRC outperforms traditional PID control in both dynamic response speed and control effectiveness,demonstrating its practical value in solving complex temperature control problems in drying rooms.
