Abstract

A new algebraic method, developed for the on-line identification of uncertain parameters in controlled linear dynamic systems, is used in the output feedback trajectory tracking. problem for a double bridge DC-to-DC power converter of the "buck" type, accomplishing a DC-to-AC power conversion for which the resistive load and the external source voltage values may be subject to sudden, unmodelled, step variations.
