The inventive process control system makes use of Optimal control (OC) and model predictive control (MPC) techniques for selection of the Expert Systems (ES) targets U. The ES target U is selected in such a way that the performance criterion J is minimized. In other words, a mathematical model of extended system given by the process P and the ES is developed. This mathematical model has hybrid nature in the sense that both continuous dynamics (mostly process) and logical relationships (mostly ES) appear in it. Controlled variables of the mathematical model are the ES targets U and inputs are the measurements y and the performance criterion J. OC and/or MPC techniques are used to compute U. <??>The optimizer of the OC/MPC selects values of the ES targets U only. This activity has lower sampling rates than selection of C, which makes the design of the OC/MPC controller easier. <IMAGE>
