As key equipment in nuclear power plant, the reactor power control system is adopted to strictly control and regulate the reactor\npower of a PWR (pressurized water reactor) in a nuclear power plant. A well-optimized predictive control algorithm based on\nSDMC (stepped dynamic matrix controller) is developed and introduced in this paper and applied to the power regulation of a\nreactor power model. In addition, the test and verification of this application is conducted by two different methods and devices:\nthe virtual verification platform and the physical DCS (digital control system). The result of the verification suggests that the\napplication of SDMC gains a better performance in the maximum dynamic deviation, adjustment time, overshoot, and so on.
