Abstract :
It is shown that the strict positive realness (SPR) condition for asymptotic stability of the continuous-time parallel model reference adaptive system (MRAS) can be removed provided that the parameter adaption law includes a proportional term and the information matrix is made sufficiently large. The present result a continuous-time counterpart of an earlier result (M. Tomizuka, ibid., vol.27, no.4, p.505-6, 1982) on the discrete-time parallel MRAS
