摘　　要：实验教学是现代教育教学活动必不可少的关键环节。文中给出基于OPC技术的Matlab与S7-200 PLC实时通信机制在A3000型过程控制实验装置中的应用方案。采用S7-200作为OPC服务器,Matlab作为OPC客户端,由Matlab实现单神经元PID控制。单神经元PID控制具有自学习和自适应能力,在一定程度上解决了传统PID调节器不易在线实时整定参数的不足,提高了控制器对系统和环境变化的适应能力。该方案使Matlab仿真不再只局限于传统的离线计算和纯数字的仿真,而易于在实际系统上实现先进算法。Experimental teaching is essential key to modern education activities .In this paper , the application plan of real-time communication of Matlab with S 7-200 PLC based on OPC technology in A3000 process control experiment device was proposed .The single neuron PID control scheme was real-ized by Matlab using S7-200 PLC as OPC server and Matlab as OPC client.The single neuron PID control had the capacity of self-learning and adaptive , thus to a certain extent , solved the difficult of traditional PID controller tuning parameters in real time and improved the adaptability of the system to environmental changes .This program made Matlab simulation was no longer confined to traditional offline computing and pure digital simulation , and easy to implement advanced algorithms in real systems .
