GENERALIZED PREDICTIVE CONTROL IN FAST-RATE SINGLE-RATE AND INPUT MULTIPLEX TYPE MULTIRATE SYSTEM

This paper discusses the designs of Generalized Predictive Control (GPC) scheme. GPC is designed in two cases; the first is a multirate system, where the sampling interval of a plant output is an integer multiple of the holding interval of a control input, and the second is a fast-rate single-rate system, where both the holding and sampling intervals are equivalent to the holding interval of the multirate system. Furthermore, the relation between them is investigated. This study gives the conditions that the fast-rate single-rate and the multirate GPC become equivalent.
