A novel fault tolerant smart system for BLDC motor based electric vehicles

Abstract

This paper presents a generalized smart Fault Detection (FD) and Gate Pulse Correction (GPC) system to enhance the BLDC drive system’s reliability to the binary hall sensor faults. Therefore, this drive system ensures a continual motor run if one of the hall sensors gets damaged. The whole drive control system is a simple digital logic circuit. The drive system with the proposed control scheme is simulated in MATLAB/Simulink environment first and extended to hardware. And the corresponding results are presented.
