M. Dahleh et M. Ricci, ON THE SPR CONDITION IN OUTPUT ERROR ESTIMATION SCHEMES, Journal of dynamic systems, measurement, and control, 115(4), 1993, pp. 704-708
In this paper we will analyze the SPR condition in output error adapti
ve estimation schemes. An idea of Tomizuka is used to reduce the restr
ictive nature of the SPR condition, and is strengthened by exploiting
certain a priori information on the uncertainty structure of the under
lying plant, which is represented by an interval plant description. Ne
w results for the analysis of these types of systems are obtained, and
are subsequently incorporated in the analysis of the adaptive system.
