基于PSO算法的生料浆配料过程的优化控制

Optimization Control of the Raw Slurry Blending Process Based on the PSO Algorithm

针对烧结法氧化铝生产流程中的生料浆配料过程的工艺特点,将PSO算法应用在配料过程中的原料分配优化问题中,并构造了惩罚函数来处理配料过程中的各种约束条件。基于PSO算法的优化控制不仅可以保证生料浆的各项工艺指标达到设定值,同时可以保证配料成本最低。在某氧化铝厂的应用结果表明,该优化控制可以取代传统的人工配料生产方式,提高了生料浆各项工艺指标的合格率,降低了配料成本,实现了优化配料,取得了显著的应用效益。

In alumina sintering production process, some materials are blended to produce raw slurry whose quality is the key factor to decide the quality of alumina production. In order to optimize the blend process, the optimal algorithm based on the PSO algorithm is used to search the most optimal amount of each material which decide the quality of the raw slurry. In order to dispose the equation restriction and inequation restriction, a penalty function is proposed as the fitness function of PSO algorithm. Application in some alumina factory shows the validity of the proposed optimal algorithm.
