Linearized Model for Optimal Controller Design of PWR Core and Its Application

Based upon the perturbation theory,a Linear Time-Invariant（LTI） model of the Pressurized Water Reactor is formulated through the linearization of the nonlinear model.A Linear Quadratic Gaussian（LQG） optimal controller is synthesized using the LTI model and simulation experiments are performed.The simulation results show that the methodology of employing the linearized model for control system design is feasible and the control performance is satisfactory.
