Abstract
In most applications where electrical energy needs to be converted to
mechanical energy, the most common direct current motors are preferred after
asynchronous motor. Since the motors used in most industrial systems are
required to produce a high development momentum, it is inevitable to draw high
currents from the grid at start times. This high starting
current must be kept under control as it increases the power consumption and
can seriously damage the stator and rotor windings of the motor. A suitable drive and monitoring system is required for this current
control operation. Fuzzy logic controller has adaptive features; it can produce
strong results in systems with uncertainties, variable parameters and load distribution.
In this study, the starting current of a serial connected DA motor fed from the
Zeta converter was first investigated by computer simulation using a fuzzy
set-PI controller. The fuzzy-tuned-PI control method was compared to the same
motor under the same conditions as conventional PI and fuzzy logic. Matlab /
Simulink software was used for simulation. According to the simulation results,
it is observed that the fuzzy-tuned-PI controller has a stronger response than
the classical PI and fuzzy logic control and the motor draws lower current at
the time of development.
