Abstract
The commenter shows that the parameter adjustment procedure proposed by J.M. Krause and P.P. Khargonekar (see ibid., vol.AC-32, p.802-10, Sep. 1987) reduces, after sufficiently exciting signals have been obtained, to a standard least-squares algorithm with a linear time-invariant filter. In reply, Krause and Khargonekar acknowledge that the commenter has demonstrated a valid and different interpretation of their two-stage adjustment law.<>
