板形误差信号分解算法是冷轧板形反馈控制系统的核心,是获得良好板形质量的关键。本文介绍了一种简单易行的最优化算法——有效集法,并将其引入到冷轧板形反馈控制中,测试结果表明该算法的计算时间小于50ms,完全满足在线板形反馈控制的要求。与最小二乘法相比,有效集法可以灵活实现多种板形控制策略,能够根据不同时刻的板形偏差并充分考虑板形调控机构的调控能力后获得最优的修正量,为冷轧板形反馈控制提供了一种更有效的方法。
Flatness error signal decomposition algorithm is the core of the cold rolled flat feedback control system, the key to good shape quality. In this paper, a simple and effective optimization algorithm, the efficient set method, is introduced and introduced into the cold rolled sheet shape feedback control. The test results show that the calculation time of the algorithm is less than 50ms, which satisfies the requirement of online form feedback control Claim. Compared with the least square method, the effective set method can flexibly realize a variety of plate-shaped control strategies, obtain the optimal correction amount according to the plate-shaped deviation at different moments and fully consider the regulation ability of the plate-shaped control mechanism, Shaped feedback control provides a more efficient method.
