Abstract :
This paper proposes a new design method for a multirate control system, where a sampling interval of a plant output is an integer multiple of a hold interval of a control input. To employ the effect of integral compensation only if there is modeling error or disturbance, two-degreeof-freedom (2 DOF) Generalized Predictive Control (GPC) in the multirate system is proposed. To this end, one-degreeof-freedom (1 DOF) multirate GPC without integral compensation is first derived, and next the 1 DOF multirate GPC is extended into 2 DOF control by using integral compensation. Numerical examples demonstrate the effectiveness of the proposed method.
