在热镀锌工艺中，镀锌层的质量及其分布受气压和气刀喷嘴到带钢表面的有效距离的控制。本文研究了如何利用现代建模、估计和控制技术来设计一种先进的气刀控制器，以改善带钢表面锌沉积质量的均匀性，降低锌消耗。提出了一种由卡尔曼滤波、刀位控制器和气压控制器组成的气刀控制算法。仿真和在线试验结果验证了该算法的可行性和可靠性。这些结果还说明了该算法独特而出色的性能，并表明每年潜在的锌消耗节省约为100万美元。
In a hot-dip galvanizing process, the mass of zinc deposited and its distribution are controlled by the air pressure and effective distance from the air knife nozzle to the steel strip surface. In this paper, we investigate how modern techniques of modeling, estimation and control can be used to design an advanced air knife controller that improves the uniformity of the deposited mass of zinc on steel strip surfaces and reduces zinc consumption. An algorithm consisting of Kalman filters and knife position and air pressure controllers has been developed for the air knife. Simulation and on-line trail results confirm the feasibility and reliability of the proposed algorithm. These results also illustrate the unique and excellent performance of the algorithm, and suggest that the potential annual saving of zinc consumption is of the order of US$1M.
