Abstract: Possible application of generic nonlinear model control (GMC) for Dabaa pressurised water reactor (PWR) type nuclear power plant is studied for the load following operations. A self-adapting controller based on a generic minimal variance strategy is utilised. The controller design is modelled as a linear second-order model with unspecified time-varying parameters. Configuration parameters are modified online using an extended least square approach with a recursive prediction sequence; the controller is implemented on an optimised model from the literature. The cooling temperature is kept as close as possible to the desired value in the load following operating mode. The position of the control rod is selected as the control variable. The proposed controller was benchmarked against the conventional rod speed programme controller (CRSP). The outcomes are promising and indicate the opportunity to implement the GMC approach for an actual nuclear power plant.
