Abstract: A real coiling temperature control system for hot rolling strips was investigated for a long time. A useful self-adaptive regulation was obtained. First before the self-adaptive calculation the initial value which combines the target with the measured information can be got by using the coiling temperature model. Then the result of the self-adaptive caculation can be used to correct the simple model in order to improve the model accuracy. For the more, some modified methods were put forward and applied into the production line. As result, the good effect was achieved.
