Abstract: The aim of this study is to design a sliding mode controller to follow the reference power trajectory, overcome the external disturbances and eliminate the chattering phenomenon in nuclear reactors. This controller is designed based on a Reduced Order Classical Neutron Point Kinetic (ROCNPK) model. This model is presented based on the measurable variables such as: the reactor power and the coolant temperature. The stability analysis of the close-loop system is performed using lyapunov method. Also, the chattering phenomenon in the control law is eliminated by using narrow-band saturation function. The proposed Reduced Order Sliding Mode Controller (ROSMC) is simulated using matlab/simulink and its performance is evaluated in different operation conditions. The simulation results illustrate proposed controller follow the reference power trajectory accurately and is satisfactory in the presence of the external disturbances.
