Performance analysis of direct torque control of permanent magnet brushless dc motor

Abstract EN

This paper recommends the direct-torque control (DTC) for Permanent Magnet Brushless DC Motor (BLDC)
motor drives.

DTC is unique productive techniques utilized in factor frequency drives to control BLDC motor.

This control strategy interduce numerous focal points like quick torque response, no need of organize change
and less reliance on the rotor parameters.

The predictable flux magnitude and torque are related to their set
values.

The torque set value is created from the produced signals at speed controller (PI controller).

The PI
parameters tuning are imperative to DTC system to enhance the performance of the system at low speeds.

This
article presents the performance analysis simulation of BLDC drive utilizing PI controllers and assessed under
different load disturbances influences in the MATLAB/Simulink program.

Simulated results are displayed,
and it is verified that the DTC control system decrease torque swell and a quicker dynamic response
