A control procedure is provided for use during a regulation stage and according
to a set point of a physical dynamic system, the set point being subject to, whilst
operating, the influence of several physical quantities represented by input parameters,
and adopting a behavior defined by at least a first physical output parameter,
obliged to take a value represented by the set point, the first output parameter
being linked to at least a first of the input parameters by a first transfer function
of the system. According to the control procedure, a characterization stage is
implemented in which at least a first inverse transfer function linking the first
input parameter to the first output parameter is experimentally determined. A modeling
stage is implemented in which the first inverse transfer function is translated
through a fuzzy logic model in the form of a first set of ranges of the first output
parameter, to each of which is attributed a specific value of the first input parameter.
The regulation stage is implemented by determining a membership of the set point
to one of the ranges of the first set, deducing from the membership and from the
fuzzy logic model an estimated value of the first input parameter corresponding
to the desired equality between the first output parameter and the set point, producing
a measured value of the first input parameter, and regulating the first input parameter
according to a difference between the estimated value and the measured value of
the first input parameter. The present invention is particularly suited for use
with electric motors.
