A NOVEL APPROACH TOWARDS HANDLING OF BLDC MOTOR DRIVE ALONG WITH FAULTY HALL SENSOR DETECTION AND REMEDIAL STRATEGY

The paper here provides a simple control system to tolerate the fault in BLDC motor resulted due to any failure of Hall Effect sensors. The proposed control system in this paper should be capable of detecting the fault, identify the fault and take remedial actions accordingly. The fault may be due to sensor breakdown or improper connection. In this paper behavior of BLDC motor is studied for Hall Effect sensor breakdown. We are studying the behavior of BLDC motor through simulation and validated first for no fault condition. Then the controller was designed in such a way that it has to detect the fault. Here simulation is done for BLDC motor for sensor breakdown in phase B for two possible faults. The proposed method designed here is to mainly maintain the performance of the motor in good running condition. The simulation results shows the correct performance of Fault tolerant control system which is designed
