摘　　要：建立基于比例-积分(PI)控制的空间堆电功率调节方法,分析单独调节反应性或外部负载的电功率控制方案。结果表明:单独调节反应性、电功率的输出存在明显的响应延迟;而单独调节外部负载则存在不稳定的电功率控制范围。因此,提出了基于共同调节反应性和外部负载电阻协同作用的空间堆电功率的比例-积分控制策略。结果表明协同控制方法可以避免单独采用调节反应性控制输出信号延迟和调节外部负载电阻控制电功率范围有限的缺点,满足空间堆电功率输出控制的要求。A proportional-integral （PI） control of space reactor electric power method is developed. The control scheme of electric power by manipulating the reactivity only or extemal load only was analyzed. The result shows that the electric power responds at a slower speed by manipulating the reactivity only. When manipulating the external load only, the electric power will be out of the control range and the system becomes unstable. Thus, an optimal PI controller of the space reactor electric power that based on coordinated control strategy on the external load and the reactivity was developed. The result shows that the coordinated control strategy can avoid the limitations of the control of electric power by manipulating the reactivity only or external load only. The coordinated control strategy can meet the basic control requirements of the space reactor electric power output.
