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

Figure 2

The exact source (blue) and the estimated source (black): (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.
