Abstract
This paper presents a practical implementation of the Fuzzy logic control to
an electrical drive system. The hardware control circuits are divided into two groups,
the first one is to determine the suitable trigger angle to the load according to their
windings resistance circuit. The second is to monitor the motor operation and runs in
order to compensate the trigger angle value when any disturbances occur at the motor.
The soft starters use the current through the stator winding of the motor as feedback,
in which the voltage is adjusted through the setting of the IGBT firing angle. The
feasibility and effectiveness of the control scheme are experimentally demonstrated
and the results are compared with the conventional soft starter controller in dynamic
responses of the closed-loop drive system.
