factor, change in control scaling factor and change in control
action scaling factor are anticipated by Ueda’s error (e),
rate of change (delta e) and its rate of change (delta U).
Note how the values are scaled in figures 5a, 5b and 5c.”
Appellant asserts (brief, page 10) that Ueda’s tuning
parameters K , K , and K tune membership functions having1 2 3
values between -K , K , and K and +K , K , and K , whereas1 2 3 1 2 3
appellant’s invention uses values that are scaled to values
between -1 and +1. Appellant further asserts (brief, page 11)
that “[n]owhere does Ueda disclose use of any scaling factors,
and certainly not the specific factors of Appellant’s
invention.”
Claim 9 recites “The method of claim 1, said fuzzy
control parameters including scaling factors for said fuzzy
logic controller.” Claim 10 recites “The method of claim 9,
said scaling factors including control error scaling factor,
change in control error scaling factor, and change in control
action scaling factor.”
We find that Ueda discloses (col. 5, line 67 through col.
6, line 4) “[s]ince the parameters K , K , K represent width1 2 3
along the horizontal axis (a fuzzy variable), the peak
