Implementation and Performance Analysis of EPLL Based Field Oriented Control Algorithm for Speed Control in Electrified Transportation Systems

Abstract

The paper presents performance analysis of speed control techniques for Induction motor and BLDC motor using EPLL based field oriented control algorithm. EPLL is an adaptive notch filter used for parameter estimation and synchronizing the control signals in rotating reference frame. It improves the overall efficiency by reducing the computational burden during the estimation of parameters. The simulation for speed control of these ac motors is implemented using Matlab/Simulink and the results demonstrate the effectiveness of the proposed system. The hardware implementation of the speed control strategy for BLDC motor is presented using C2000 DSP microcontrollers and DRV8301 based inverter. The real-time implementation of control algorithm using DSP controller is discussed for speed control of BLDC motor.
