Repetitive process based indirect-type iterative learning control for batch processes with model uncertainty and input delay

Subject and Keywords:

batch processes ; iterative learning control ; input-delay ; repetitive processes ; robust H? control ; linear matrix inequality

Abstract:

This paper develops an indirect iterative learning control scheme for batch processes with time-varying uncertainties, input delay, and disturbances. In this paper, a predictor based on a state observer is designed to estimate the future state and to compensate for the input delay. ; Then a feedback controller based on the estimated state and the set-point error is used to track the specified reference trajectory, where, of the options available, a robust H? controller is designed in the presence of time-varying uncertainties and load disturbances. ; Then a proportional plus derivative type iterative learning control law is designed. An injection molding process model demonstrates the new method`s effectiveness, and a comparison with a direct-type design is given. In this alternative approach, all design objectives are simultaneously considered.
