Research on intelligent dosing control of coal processing plant flotation based on internal membrane decoupling control

为改善煤泥浮选性能,提出一种内膜解耦控制方法。针对浮选过程多变量特点,将解耦控制和内膜控制结合,对浮选过程加药量进行优化,以提高系统响应速度和浮选性能。为评估所提方案,在选煤厂浮选加药实际生产场景中,使用该方法进行加药优化,验证了该方法的有效性。结果表明,该方法在控制浮选生产稳定和模型失配方面更具优势。

In order to improve the flotation performance, an internal membrane decoupling control method is proposed.The decoupling control and internal membrane control are combined to optimize the dosing rate of the flotation process to improve the system response and flotation performance for the multivariate characteristics of the flotation process.In the experimental part, to evaluate the performance of the proposed scheme, the method is used to optimize the dosing for the actual production scenario of flotation dosing in coal processing plants, and the effectiveness of the method is verified.The experimental results show that the method has better advantages in controlling flotation production stability and model mismatch.
