The purpose of this study is to verify the applicability of the modal iterative error correction method for equation discovery. This method is effective for solving inverse problems with strong discontinuities. Additionally, this method can remove null modes to obtain a simple equation without unnecessary terms. The outline and details of the method are explained. Next, the applicability of this method through an example problem. As a result, it is confirmed that identification of equation composed of only essential terms from input/output results of unknown input/output systems was possible by a modal iterative error correction method.
