Shaft Loom Tension Control Car Marks Compensation Application

The design of the computer control system of loom plays an important role in the loom development, and start mark compensation is the key technology. In this paper, the main part of the shaft loom computer control system is carried out systemically, including the software and hardware design of the loom system with encoder and the let-off system, the let-off controller algorithm, and the start mark compensation. On the base of former research, an improvement of the communication system is put forward by the author, the easy communication is ensured. An improvement algorithm for the let-off controller is discussed, and the way for applying of Fuzzy PID in let-off system is also shown. The start mark compensation of the let-off system is mainly studied by the means of digital synthesize for the first time, a systemic research for the explanations of its coming out and the elimination is carried out, and the universality of this method is discussed in the last. The way of start mark compensation has a great effect on the performance of the loom system. The settle of this problem will give much improvement to the loom development of our country.
