JPEEE1454 Sensor less Control of BLDC Motor Drive for an Automotive Fuel Pump Using a Hysteresis Comparator

  1. 1. Sensor less Control of BLDC Motor Drive for an Automotive Fuel Pump Using a Hysteresis Comparator Abstract: This paper develops the brushless dc (BLDC) Motor sensor less control system for an automotive fuel pump. The sensor less techniques that are based on a hysteresis comparator and a potential start up method with a high starting torque are suggested. The hysteresis comparator is used to compensate for the phase delay of the back EMFs due to a low pass filter (LPF) and also prevent multiple output transitions from noise or ripple in the terminal voltages. The rotor position is aligned at standstill for maximum starting torque without an additional sensor and any information of motor parameters. Also, the stator current can be easily adjusted by modulating the pulse width of the switching device during alignment. Some experiments are implemented on a single chip DSP controller to demonstrate the feasibility of the suggested sensorless and start up techniques.
