基于PLC的烘筒烘燥机控制系统设计

Design of Control System of Drying Pit Based on PLC

介绍了由PLC应用系统构成的印染厂烘筒烘燥机控制系统方案,详细阐述了控制系统的软、硬件结构设计。该控制系统采用模糊PID算法,实现了回潮率在线测控。实践表明,该系统结构简单、自动化程度高、运行可靠,极大地提高了印染厂的自动化水平。

A drying pit control system that was composed of the PLC applied system was introduced in the printworks. The design of the structure of hardware and software was discussed in detail. In this system, the online measuring and controlling of moisture was realized by the fuzzy PID algorithm. The application process indicated that the system was simple, highly reliable and highly automatic. The automation level is improved greatly in the printworks.
