final rejection of claims 7-16 and 18-20, all of the claims
pending in the application. Claims 1-6 and 17 have been
cancelled.
We affirm-in-part.
The disclosed invention is directed to a fuzzy logic control
system for controlling a turboshaft engine as can be understood
from claim 7 reproduced below.
7. A control system for controlling a turboshaft or an
aircraft engine comprising:
a plurality of low-level controllers adapted to receive
engine signals, each of said low-level controllers operable
to output a control variable value that is based upon said
received engine signals; and
a fuzzy logic hierarchical controller connected to said
plurality of low-level controllers to receive each of said
control variable values, said fuzzy logic hierarchical
controller being adapted to generate a single output value
for each control variable which is used for controlling said
aircraft engine, the single output value is an aggregation
of said control variable values received from said plurality
of low-level controllers, wherein the aggregation is a
weighted sum of said control values.
The examiner relies on the admitted prior art in the
specification and the following reference:
