4　板形控制研究板形的最终目标是实现板形自动控制 ,即通过板形控制系统使得轧后板形与目标板形相符合。板形控制系统是一个有惯性、有滞后、多扰动、多变量、强耦合的复杂工业控制系统 ,因此 ,随着生产的发展和技术的进步 ,传统的控制已不能满足其要求 ,于是设计者必须在寻求 4 shape control research The ultimate goal of shape is to achieve the automatic control of the shape, that is, through the shape control system makes the shape of the rolling plate and the target shape is consistent. As a complex industrial control system with inertia, hysteresis, multi-perturbation, multivariable and strong coupling, the control system of the shape control system can not meet the requirements of traditional control with the development of production and the advancement of technology. Therefore, the designer Must be seeking
