This paper reports on experiments in which the efficacy of combining proportional-integral-derivative feedback methodologies with the MIT-SNL Period-Generated Minimum Time Control Laws that were demonstrated for the safe maneuvering of reactor neutronic power on periods as short as 1.0 s under conditions of closed-loop digital control. It is shown that proportional feedback cannot compensate for errors in the measurement of reactivity and that the addition of integral action corrects for this deficiency. The need for controllers of safety-constrained systems to be capable of not only compensating for perturbations but also of diagnosing them as to cause is discussed.
