摘　　要：基于PLC的温度控制系统以三菱FX2N型PLC为控制核心,由扩展模块FX2N-4AD-TC,FX2N-2DA,热电偶组成。根据已经建立的模糊语言变量赋值表和模糊控制规则,进行模糊推理和模糊判决,建立离线的模糊控制查询表,并给出电阻炉温度模糊控制的相关程序。采用Fuzzy-PID复合控制,系统同时获得良好的动态性能和稳态性能。Based on the PLC, temperature control system, which is composed of the input, output expansion module FX2N-4AD-TC, FX2N-2DA, the thermo-element, mainly takes Mitsubishi FX2N PLE as the control core. According to fuzzy language variable assignment table which is already established and fuzzy control rule, the fuzzy reasoning and the fuzzy decision are conducted to establish the off-line the fuzzy control query table, and give the resistance furnace temperature fuzzy control procedures. Using Fuzzy-PID compound control, the system gets a good dynamic performance and steady performance.
