摘要：
Methods and planning systems used to schedule gain matrices for process control loops and determine optimal values for manipulated variables according to a minimum cost function. A cost function is calculated for each of a predetermined number of plans as a sum of partial cost functions calculated over a predetermined number of projections in a horizon. Each partial cost function after the initial projection of a plan is calculated using a scheduled gain matrix. The gain matrix can be scheduled for each projection by selection from a predetermined set of gain matrices or can be calculated in real time during the calculation for each projection.
