In the present scenario, utilization of BLDC drives are
increasing rapidly, as a result of more efficiency, more power density,
normal to control and great inertia torque ratio. This rag proposes a
concept of sensor less
control of drive using Fuzzy based DTC system. An indirect flux control
proposed in this rag is similar to the direct
torque controller for controlling of BLDC motor by the reference signals
from the direct axis currents. A fuzzy regulator also proposed in this rag
for better controlling of brushless DC drive. Simulink/Matlab is used to
test the proposed DTC-Fuzzy based BLDC drive.
Keywords: BLDC Motor, Fuzzy Controller, DTC technique and PWM
