    "abstract": "A supersymmetric class of free damped oscillators with three parameters has\nbeen obtained in 1998 by Rosu and Reyes through the factorization of the Newton\nequation. The supplementary parameter is the integration constant of the\ngeneral Riccati solution. The estimation of the latter parameter is performed\nhere by employing the recent adaptive observer scheme of Besancon et al., but\napplied in a nonstandard form in which a time-varying quantity containing the\nunknown Riccati parameter is estimated first. Results of computer simulations\nare presented to illustrate the good feasibility of this approach for a case in\nwhich the estimation is not easily accomplished by other means",
