A robust nuclear reactor power controller was developed by using a novel robust guaranteed cost control method proposed in this paper to address the instability and insufficient control precision, which was caused by the uncertainty of nuclear reactor model and randomness in real operation condition. The state feedback matrix was obtained by solving linear matrix inequality. Kalman filter was constructed to address the problem that some state variables could not be measured in real system. Loop transfer recovery method was used to make the transfer function of the whole system to approach the target feedback loop transfer function as close as possible. The system simulation indicated that the controller designed based on this method could follow the appointed power signal exactly. Furthermore, the control system had good robustness characteristics and presented good control accuracy to meet the design requirements.
