Abstract
This Paper introduces a self－adaptive tension control system used for the unwinder in a polyesterfilm slitter．Siemens S5－115U PLCis used in the system and 6SE70 vector control converter is used as its ACdriver．Several measured signals are transmitted to PLCvia ET－200 distributed I／Omodule and Profibus－DP．Inthis paper the tension controlprinciple of the unwinder is introduced．Because the roller diameter varies widely，its moment of inertia also varies wildly．For this reason the principle of self－adaptive control is used in the system．The SR loop of the system is made up of PLC，Converter and photoelectricity encoder．In the controlchannel of the SRloop a parameter is chosen，which is proportionalto the square of the roller diameter，to compensate the variation of the moment of inertia．By this way the SRloop can possess good dynamic properties inthe whole time during the variation of the roller diameter．Finally the good tension controleffect is guaranteed．关键词
