Development of a Coordinated Control Strategy for Space Reactor Based on PI Controller

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 external 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.
