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 power regulation method based on Proportional-Integral (PI) control is established to analyze the control scheme of electric power which regulates reactivity or external load separately. The results show that there is a significant response delay in the output of the electric power when adjusting the reactivity alone. However, the control range of the unstable electric power exists when the external load is adjusted separately. Therefore, a proportional-integral control strategy based on the co-operation of the reactivity and the external load resistance is proposed. The results show that the synergetic control method can avoid the disadvantage that the range of electric power is limited by adjusting the output delay and adjusting the external load resistance separately to meet the requirements of space power output control.
