Berkowitz Peter N, Papadopoulos Michael N, Colwell Larry W, Moran Martin K: Multivariable process control method and apparatus. Continental Controls, December 29, 1997: EP0813699-A1

On-line control of a process is achieved by feedforward computations of manipulated variables setpoints (SP) modified during each of frequent optimization cycles by feedback trim (84) determined by actual versus predicted effects of setpoints changes on the process controlled variables. Process, eco ...
