Embodiment Construction
[0017] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.
[0018] The hydraulic pressure-roll gap servo system of the present invention is adjusted so that when the roll gap change step value of 20 microns is given near the minimum working pressure of the system, the rise time is τ 1 Second.
[0019] In this paper, for a certain variable B, the expression in the k-th period is B(k), the expression in the k-1 period is B(k-1), and the expression in the k+1 period is B(k+1) . If the variable B is constant, it is directly represented by B in the k period.
[0020] Further, the method specifically includes the following steps, in the kth execution cycle of the program written according to the method:
[0021] 1. The actual pla...
