Since the invention of Fuzzy logic and fuzzy control, the latter has been growing in spread
and importance in many applications and devices in many life aspects. This maybe due to
the easy use of a fuzzy control system, and for being far of math co
mplications. Even if the
plant model is unknown, a self-organizing fuzzy controller (SOFC) can improve the
response of an already exist linear control table, or even can build a control table from
scratch, by assessing current performance of the controller and adjusting the control table
accordingly. This paper provides a simple article that shows how to design and use a self organizing
fuzzy controller, through a simulation example using MATLAB & Simulink
in which a variable torque loaded DC motor speed regulation is done. The simulation
showed the ability of the controller to provide a good response and decrease speed error by
a notable amount at load torque changing times. This paper can be used as textbook
material for students or researchers interested in the field of adaptive control, especially
self-organizing fuzzy control.
