【摘要】 本文介绍了利用PLC实现对液压性能试验台进行模糊控制的过程。试验台的控制系统属于一个双输入双输出的系统,而且系统控制量的控制论域是随着被测物体的测量范围的不同而不同,因此,在实现控制策略时,对系统参数进行了模糊解耦,并对模糊控制规则表中的输出量进行了参数修正。最后,阐述了模糊控制算法在PLC上实现的过程。更多还原

【Abstract】 This paper introduced how to use the PLC to realize the fuzzy control of the hydraulic pressure experimentation platform. The control system of the experimentation platform is the system of two inputs and two outputs, and the control variable’ s value can be changed in the different control range. To the different measure object have the different measure range. Therefore, while realizing control strategy, we must decompose the fuzzy variable’ s correlation, and through adjust the table of the fuzzy control rules to achieve the revise of the control parameter. At last, the article expatiate the process of the fuzzy control arithmetic realized on the PLC.更多还原
