Design of Fuzzy-PID Control System Based on Kingview
YANG Yun-fei (Department of Automation,Changshu Institute of Technology,Changshu 215500,China) Abstract:In the production of industry DCS system is more and more widely applied. But most HMI software only supplies single PID control component and lacks advance control algorithm. Temperature is one of the important control parameters. It has characters of nonlinearity, changing with time and lagging. This article combines fuzzy control with PID control algorithm by applying Kingview command language function to realize PID parameters can be self-adaptive on line. It can meet good control performance. Key words:DCS; king of view; command language function; fuzzy-PID; self-adaptive |
