Fuzzy logic offers nowadays an interesting alternative to the designers of
non linear control laws for electrical or electromechanical systems. However, due to
the huge number of tuning parameters, this kind of control is only used in a few industrial
applications. This paper proposes a new, very simple, on-site tuning strategy for a PID-like
fuzzy logic controller. Thanks to the experimental designs methodology, we will propose
sets of optimized pre-established settings for this kind of fuzzy controllers. The proposed
parameters are only depending on one on-site open-loop identification test. In this way, this
on-site tuning methodology has to be compared to the Ziegler-Nichols one's for
conventional controllers. Experimental results (on a permanent magnets synchronous motor and on a
DC/DC converter) will underline all the efficiency of this tuning methodology. Finally, the field
of validity of the proposed pre-established settings will be given.
