Steady-State Analysis of Industrial MPC Controllers

  • 1. STU in Bratislava
  • 2. Slovnaft, as.


This work deals with analysis and maintenance of steady-state performance of model predictive controllers. The aim is to use information about input and output constraints of the ideal controller and of the controller actually applied by the operators – some of them are either loosened or tightened based on actual operating conditions. This can have impact on profitability of the process. The procedure is applied to a simplified model of controller implemented at production unit at SLOVNAFT, a.s. refinery. The studied controller processes the total of 47 manipulated, disturbance, and output variables. The analysis provides information on how to move the constraints of the controller to reach the optimal operating point. Python programming language is used to create the application with the graphical user interface that is actually used at the refinery.
