An identification algorithm is proposed based on the fact that the output of system happens to be decomposed into a product of an exponential function and a periodic function. The former contains information of the damping coefficient, while the latter does not. The convergence and error analysis are also developed. Three examples, namely an anti-stable wave equation with boundary anti-damping, the Schr\\\"odinger equation with internal anti-damping, and two connected strings with middle joint anti-damping, are investigated and demonstrated by numerical simulations to show the effectiveness of the proposed algorithm.", "revisions": [ { "version": "v1", "updated": "2016-05-17T09:04:32.000Z" } ], "analyses": { "subjects": [ "35R30", "65M32", "65N21", "93B30" ], "keywords": [ "initial value", "simultaneous identification", "damping coefficient", "boundary measurement", "middle joint" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
