Several analytical model reduction techniques have been proposed in the literature over the past few decades. We introduce the application of the Schur model reduction method to design a reduced-order, robust controller for the Egyptian Second Testing Research Reactor (ETRR-2). The linear matrix inequality approach is used to design a robust, low-order H state feedback control system and a robust H observer-based controller to control the reactor power. A comparison between the proposed controllers and the actually used conventional proportional-plus-derivative controller is presented based on the simulation of the full-order nonlinear model. Results show the effectiveness of H observer-based state feedback for control of the reactor power at different operation conditions and that it guarantees the system stability.
