Experimental demonstration of H∞ filter performance for dynamic compensation of rhodium neutron detectors

This paper describes the experimental demonstration of the theoretical result of the previous work on LMI (linear matrix inequality) based H∞ filter for time-delay compensation of self-powered neutron detectors. The filter gains are optimized in the sense of noise attenuation level of H∞ setting. By introducing bounded real lemma, the conventional algebraic Riccati inequalities are converted into linear matrix inequalities (LMIs). Finally, the filter design problem is solved via the convex optimization framework using LMIs. The experimental measurements of rhodium detector signal from a research reactor show that the predicted theoretical filter performance is verified by showing successful reconstruction of the reference power signal.
