ABSTRACT
This
paper proposes a new approach to direct torque control (DTC) method for
brushless direct current (BLDC) motor drives. In conventional DTC method, two
main reference parameters are used as: flux and torque. In this paper, the new
approach has been proposed to improve the BLDC motor dynamic performance. A
main difference from the conventional method of it was that only one reference
parameter (speed) was used to control the BLDC motor and the second control
parameter (flux) was obtained from speed error through the proposed control
algorithm. Thus, the DTC performance has been especially improved on systems
which need variable speed and torque during operation, like electric vehicles.
The dynamic models of the BLDC and the DTC method have been created on Matlab/Simulink.
The proposed method has been confirmed and verified by the dynamic simulations
on different working conditions.
