A model-based predictive control approach to repetitive control of continuous processes with periodic operations

A novel model-based predictive control (MPC) method is developed with the a im of applying it to periodic process control problems. By borrowing concep ts From repetitive control (RC), we endow the MPC method with the ability t o make continuous period-to-period improvements. The method uses a linear t ime-varying system description of a periodic process and can handle constra ints on inputs and outputs. Some numerical examples are shown to illustrate performance improvements that can be achieved by the new method over the c onventional MPC and RC methods. (C) 2001 Published by Elsevier Science Ltd.
