Applied study of coordinate control of nuclear-power system

On the basis of traditional PID controller, coordinate controller is introduced, which formed the control system of nuclear power plant. The control system is applied to the nuclear power plant and processed simulation experiment. The simulation results show that the overshoot of the primary water's average temperature and exit steam' pressure after applying the coordinate control system is smaller than that of the traditional PID control system. The steady time is shortened, while the rise time of turbine power is a little longer. But the peaking overshoot turns smaller. (authors)
