Abstract:
A system, method, and article of manufacture suitable for determining setpoints of the control variables to optimize the process while taking into account the process-limiting variables in applications where responses are highly non-linear. In a preferred embodiment, the method comprises determining an actual rate of change of a performance limiting process parameter; calculating a predicted rate of change for the performance limiting process parameter for a predetermined future time interval; and adjusting a setpoint for the control variables to optimize the process while taking into account the performance limiting process parameter using the actual rate of change and the predicted rate of change.
