Improved Target Calculation for Model Predictive Control
In industrial Model Predictive Control (MPC) applications, it is common to perform target calculation at each sample instant. The purpose of the target calculation is to translate operational targets supplied by higher level optimization functions into control targets that are feasible in the face of current disturbances. This paper shows that the commonly used target calculation formulation is flawed, and that this can lead to significant economic loss. A method for dealing with the identified problem is proposed.
