Xenon shutdown model

IV. EXAMPLE WITH CONTROL CONSTRAINTS A. Xenon Shutdown Model... 

The disagreement between published results for dynamic programming and the optimum control theory as applied to the xenon shutdown model is somewhat disturbing, and this difference in the form taken tends to obscure the issue. Let us show, using the Pontryagin method on the b form of the problem, that the two statements are, in fact, equivalent. 

One danger in a brief review article is that the examples given may be so slight in content that significant aspects of the theory may not be adequately illustrated. We have chosen, therefore, to confine the examples to a single model or problem, namely, the shutdown of a nuclear reactor subject to xenon poisoning, in order to save having to develop the details of the...
