摘　　要：目前,现场总线被广泛应用于制造业、流程工业、楼宇、交通和电力等自动化领域。针对在现场总线环境下如何实现先进控制算法的问题,提出一种基于模糊自适应PID算法及Profibus-DP总线控制器的设计方法,使Profibus-DP从站和模糊自适应PID算法相结合构成了网络型智能化控制器,以实现PID参数的快速在线自调整功能。同时通过实验证明,该控制器的控制系统工作稳定,控制效果显著。At present, fieldbus has been widely used in manufacturing, industrial process, building and transportation automation as well as electric power automation. Aiming at the topic about how to implement advanced control algorithm under fieldbus environment, the design meth- od based on fuzzy adaptive PID and Profibus-DP bus controller is proposed, thus the Profibus-DP slave station and fuzzy adaptive PID algorithm are combined to construct networking intelligent controller to realize fast speed online adjustment for PID parameters. The experiments verify that the control system is operating stably with outstanding control results.
