| 摘 要： | 将先进的智能控制方法与PLC控制器相结合，根据二维模糊控制器的工作原理和PLC的特点，提出了一种用PLC实现模糊控制的设计方法。该方法采用MATLAB的模糊逻辑工具箱进行分析和计算，离线生成模糊控制查询表，借助PLC的存储器间址寻址方式实现模糊控制算法。运用PLCSIM仿真软件测试该算法，证明该控制器的模糊输入和解模糊输出是正确的。

| Abstract: | A design method for achieving fuzzy control with PLC is given by combining advanced intelligent control methods with PLC controllers and basing on the working principle of two-dimension controllers and the characteristics of PLC. It achieves the fuzzy control arithmetic by adopting the MATLAB fuzzy toolbox for analysis and calculation, creating the fuzzy control querying table off-line, and with the help of indirectly addressing the memories of PLC. It is proved that the fuzzy input and anti-fuzzy output is correct by testing the arithmetic with the PLCSIM simulation software. |
