Extended Generalised Predictive Control incorporating Feedforward

Abstract

In this paper, we present an extension of the Generalised Predictive Control which incorporates feedforward action. This extended controller, referred to as GPCF (extended Generalised Predictive Control incorporating Feed-forward), is applicable to situations when there are measurable disturbances affecting the process output. Simulation studies together with an application involving real-time control of a heat-exchanger pilot plant demonstrate that the GPCF offers improved regulation in situations where there are measurable disturbances.
