Attorney, Agent or FirmInternational ClassesB01J 19/00 (20060101)C08F 10/00 (20060101) G05B 15/02 (20060101) G05B 13/02 (20060101) AbstractIn a process in which a first process variable is manipulated so as to maintain a second process variable substantially equal to a desired value for the second process variable, a set point for the first process variable is generated based on the difference between the actual value of the second process variable and the set point for the second process variable. The magnitude of the set point is determined by the probability that the second process variable may reach an undesirable value and thus control using the set point takes into the consideration the fact that large control actions may be required under some circumstances and minimal control actions may be required under other circumstances in a process. |
