Abstract:For more improve the dynamic control capabilities of the nuclear power, this paper put forward to apply the algorithm of the nonlinearmodel predictive coordinated control in the main parameters of the nuclear power, including control structure and the design of controller in the base of expounding the math model of the turbine and the once-through steam generator. The simulation result show that the change of the gas turbine speed and the steam pressure under the algorithm of the nonlinear model predic-tive coordinated control can fast stabilize. So it show that the algorithm of nonlinear model predictive coordinated control can better control the output of the main parame-ters of the nuclear power and get the better control effect.
Key words:nuclear power; multivariable nonlinear model predictive coordinated control; simulation
