Four methods for sensor selection validated and compared on the H2/O2 network for short observation length. Estimation error η for (a) Method 1, (b) Method 2, (c) Method 3, and (d) Method 4. The histograms correspond to the estimation errors for all possible combinations of the sensor nodes. The network is sufficiently small that exhaustive calculation of all combinations is possible in this case. The blue line represents the estimation error for the optimal sensor selection. The results are obtained for N = 50, h = 10−13, and the IRK model.
