Small PWR can be used for power generation and heating. Considering that small PWR has the characteristicsof flexible operating conditions and complex operating environment, the controller designedbased on single power level is difficult to achieve the ideal control of small PWR in the whole range ofcore power range. To solve this problem, a flexible switching controller based on fuzzy controller andLQG/LTR controller is designed. Firstly, a core fuzzy multi-model suitable for full power range is established. Then, T-S fuzzy rules are designed to realize the flexible switching between fuzzy controller andLQG/LTR controller. Finally, based on the core power feedback principle, the core flexible switchingcontrol system of small PWR is established and simulated. The results show that the flexible switchingcontroller can effectively control the core power of small PWR and the control effect has the advantagesof both fuzzy controller and LQG/LTR controller.
