提出一种在现场总线网络控制新环境下的自适应PID控制器研究与实现方法。通过对历史数据的分析和在线辨识被控对象在重要频率点的频率特性,在DeviceNet网络环境下设计自适应PID控制器,实现现场运行处于稳定、安全、最优的运行工况。
This paper presents a method to study and realize the adaptive PID controller based on the new environment FieldBus networked control. The optimization response of important frequency is estimated by the history date analysis. Then, the adaptive PID controller is designed to realize stable, safe and optimization work in present situation at the circumstance of DeviceNet.
