Methods and apparatus for model predictive control in a real time controller

摘要

Methods (300) and apparatus for controlling load on a machine (30) are provided. The method includes determining (304) a maximum value of a process variable using a predictive model of the machine while holding a control output associated with the process variable substantially constant over a prediction period, incrementing (312) the control output if the determined maximum value of the process variable is within an allowable limit range, and setting (318) the control output to the last value of the process variable that did not cause the process value to exceed the allowable range.
