An Adaptive Observer-Based Algorithm for Solving Inverse Source Problem for the Wave Equation

Figure 3

The exact source (solid blue line) and the estimated one using observer solution (red) and modified-Tikhonov (green): (a) and (b) present the noise-free case with respect to full measurements and partial measurements, respectively. (c) and (d) show the noise-corrupted case with respect to full measurements and partial measurements, respectively. In the partial measurements cases, of the state components are taken from the end.
