Research on Global Fuzzy Control Method over Reactor Power
Among reactor power control methods, the most commonly used one is Proportional-Integral-Derivative (PID) control method, though it is very easy to carry out, the disadvantage of this method is that the control speed is slow and the overshoot is large. Fuzzy control method of reactor power can ameliorate the PID method, but not all of them performances effective enough. After analyzing the reason why the control speed was so slow and why the large overshoot occurred under load drop working condition, this paper tabled a new method to control the reactor power--the global fuzzy control method, then control simulation was made on the reactor coolant system simulation platform. The simulation results showed that the global fuzzy control method controlled fast and had a small overshoot under load drop working condition, and almost didn’t influence the steady-state error.
