Appeal No. 1997-1111 Page 3
Application No. 08/105,899
BACKGROUND
The appellant's invention relates to a method and
apparatus for fuzzy logic control with automatic tuning. An
understanding of the invention can be derived from a reading
of exemplary claim 1, which is reproduced as follows:
1. A method of automatically tuning a fuzzy logic
controller used to control a process in a predetermined
manner, said process producing at least one process variable
and having at least one control action input connected to said
fuzzy logic controller, said method comprising:
determining from said process a plurality of dynamic
process
characteristics for tuning a proportional integral
derivative controller;
calculating fuzzy control parameters as functions of said
dynamic process characteristics for tuning said
fuzzy logic controller; and
tuning said fuzzy logic controller using said fuzzy
control
parameters for controlling the process.
