Abstract

Abstract: Against large delays and uncertainty of electric furnace’s controlled object model，research and design based on Profibus-DP network structure of the new PID controller are focused on.An adaptive PID algorithm design based on fuzzy genetic algorithm in fieldbus environment is proposed.The Profibus-DP slave and complex combination of fuzzy adaptive PID algorithm constitute a network of genetic adaptive fuzzy PID controller.The fast online auto-adjustment function of PID parameters is achieved.MATLAB simulation is used，and through three-way electric heater experiment the fuzzy genetic algorithm is proved.PID controller is stable in the PROFIBUS field bus communication system，and the control effect is remarkable，better than that of the conventional PID controller.

摘要： 针对电加热炉被控对象的大延迟、模型不确定性，着重研究和设计了一种基于Profibus-DP网络结构的新型PID控制器。提出一种在现场总线环境下基于模糊遗传自适应PID的算法设计。使Profibus-DP从站和复合模糊自适应PID算法相结合构成了网络型模糊遗传自适应PID控制器，以实现PID参数的快速在线自动调整功能。并用MATLAB进行仿真，同时通过三路电加热炉实验证明。该PROFIBUS现场总线通信系统中PID控制器工作稳定，控制效果显著，优于常规PID控制器。
