Dear User,
It is possible to implement any iterative algorithm even in matrix form in SCL ,if they can be explained and structured in basic numeric formula. To implement these formulas , you can use basic instructions in SCL or write your own function blocks for repeated tasks. The point is, such extensive calculations are not necessary for a real industrial cases while most of MPC tools are linked via OPC to the automation system and calculation load is in an engineering station.Even in PCS 7 that has an embedded lean MPC function block,after data gathering , all optimization and calculations are done in engineering station and results(matrices) are loaded into the block in PLC. For a clear explanation, please read section 1-4 of the attached file. I hope it helps, hdhosseini AttachmentWP_PCS7_APC_EN.pdf (162 Downloads) |
