Advanced deviation correcting system of fabric strips based on repetitive control

In the fabric strip production process, a periodical S-shape deviation of the strip often occurred. Focusing on this issue, through analyzing the mathematical model of the strip unwinding web guiding system, and according to the good performance of the repetitive control in tracking periodic signal, this paper presents an advanced deviation correcting system based on adaptive repetitive control and feedforward control. The composition and working principle of the system are advanced. The design method of deviation correcting algorithm is introduced. The MatLab simulation results have verified its advantages in correcting the periodical S-shape deviation. In addition, this paper introduces the realization of the embedded repetitive deviation controller with MCF52235 chip as its core. This system also can be applied in the intermediate and rewinding web guiding system.
