Abstract
This research is to deal with the nonlinear control issue for power regulations of the pressurized water reactor core in nuclear power plants. Based on modeling a nonlinear pressurized water reactor core using the lumped parameter method, its linearized model is achieved through the small perturbation linearization way. The H∞ output-feedback control with analysis of weight functions and linear matrix inequalities solving method is used to contrive a robust controller of the linearized core model. Besides, general laws of selecting weight functions in H∞ control are summarized. The solved H∞ output-feedback controller is applied to the nonlinear core model. The nonlinear core model and the H∞ controller construct the nonlinear core power H∞ control system. Eventually, the nonlinear core power H∞ control system is simulated, and simulation results show that the nonlinear control system is effective.
