Abstract

This paper investigates steady state and transients' performance of Brushless Direct Current Motor (BLDC) motor and collates the performance of Proportional Integral (PI) and Proportional Integral Derivative (PID) Controller. Speed and torque behavior is most valuable nowadays for home appliance and other applications. The torque in motor is produced with effect of magnetic field and current. Magnetic field is generated in motor by the strong permanent magnet, and motor current depends upon voltage control and Eb, which is done by field and speed motor. In order to obtain required torque and speed at a particular load, current required must be controlled. The transient or dynamic response analysis is done with transfer function of BLDC motor obtained by the Laplace transform of equivalent circuit equation. The trapezoidal type BLDC machine is controlled using 3-phase Inverter Bridge. The commutation sequence is done with hall sensor and gate pulses. The simulation work is done in MATLAB/ Simulink software and mathematical model is evaluated. The analysis is done to know the performance of how quickly the transient reduces and gives smooth operation for various applications.
