| 英文摘要 |
| This paper takes the background of cobalt oxalate synthesis in cobalt hydrometallurgy process, and an adaptation
optimization strategy for mean particle size of cobalt oxalate based on multi-way partial least squares (MPLS) model
is studied. Firstly, the MPLS algorithm is used to build the data model of mean particle size of cobalt oxalate. In order
to overcome the problem that it is difficult to obtain the optimal manipulated variables under model uncertainty, a
modifier-adaptation strategy based batch-to-batch optimization method is proposed to make the iteration results converge
to the practical optimal operating point. Additionally, T2 statistic soft constraint is used to confine the optimal solution in
the valid region of the data-driven model. The simulation results show that the proposed method can efficiently solve the
batch-to-batch adaptation optimization problem for cobalt oxalate synthesis process, and better optimization results can be
achieved compared with traditional two-step approach and iterative learning control (ILC). |
