説明

The purpose of this paper is to elaborate a closed-loop digital control system to regulate a reactor during commanded changes of power level, making use of the optimal control and trajectories derived in the previous paper. Simple application of this optimal control scheme alone would not permit satisfactory control of the reactor, on account of various external disturbances that would affect the control in actual practice. This dif-ficulty has been overcome by linearizing the system equations around the optimal control and trajectories derived as above, and thereto applying modern control theory.<BR>The feedback control system is first examined for a case where all requisite state variables are accessible. Then for the case where not all state variables are thus acces-sible, a method is devised for estimating the inaccessible variables. The estimates are obtained by detecting the accessible state variables a given number of times during each control stage, using the generalized inverse.<BR>A closed-loop system is constituted by incorporating this method of estimation into the feedback circuit. The resulting system is shown to provide amply satisfactory per-formance in terms of response time and the accuracy.
