摘要: The present paper introduces a novel sensorless control of brushless dc permanent magnet (BLDC-PM) motor based on I-f principle for starting (from any initial position) with seamless commutation to BEMF zero crossing detection above certain speed. method assures fast response and the criteria switching speed short transients. This way, general drives, even notable load torque at start, will although after hesitation depending position rotor. Several scenarios were simulated in Matlab/Simulink ( Plecs Library) confirm proposed strategy. Experiments are ongoing.
