为了进一步提高核动力装置蒸汽轮机的动态控制性能,在阐述了核动力装置蒸汽轮机的数学模型的基础上.提出将广义预测自校正控制算法应用于蒸汽轮机的转速控制中,包括控制结构和控制器设计.仿真结果显示当蒸汽轮机经历较大的工况变化过程时,广义预测自校正控制律比经典PID控制律下的蒸汽轮机相对转速变化响应要快10 s左右,而经典PID控制律下的相对转速值要比广义预测自校正控制律多出1%～2%的超调.表明所采用的广义预测自校正控制算法能够较好的控制核动力蒸汽轮机转速的输出,可以获得较好的控制效果.

Simulations research of the global predictive control with self-adaptive in the gas turbine of the nuclear power plant

For further improving the dynamic control capabilities of the gas turbine of the nuclear power plant,this paper puts forward to apply the algorithm of global predictive control with self-adaptive in the rotate speed control of the gas turbine,including control structure and the design of controller in the base of expounding the math model of the gas turbine of the nuclear power plant.The simulation results show that the respond of the change of the gas turbine speed under the control algorithm of global predictive control with self-adaptive is ten second faster than that under the PID control algorithm,and the output value of the gas turbine speed under the PID control algorithm is 1%~2% higher than that under the control algorithm of global predictive control with self-adaptive.It shows that the algorithm of global predictive control with self-adaptive can better control the output of the speed of the gas turbine of the nuclear power plant and get the better control effect.
