摘要

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 controlleris designed based on a Reduced Order Classical Neutron Point Kinetic (ROCNPK) model. This model ispresented based on the measurable variables such as: the reactor power and the coolant temperature. Thestability analysis of the close-loop system is performed using lyapunov method. Also, the chatteringphenomenon in the control law is eliminated by using narrow-band saturation function. The proposed ReducedOrder Sliding Mode Controller (ROSMC) is simulated using matlab/simulink and its performance is evaluatedin different operation conditions. The simulation results illustrate proposed controller follow the referencepower trajectory accurately and is satisfactory in the presence of the external disturbances.
