Abstract
The adaptive and non adaptive nonlinear back stepping control approach for a BLDC motor drive is discussed and analyzed. Then, the sensorless method advances are reviewed and recent developments in this area are introduced with their inherent advantages, including the analysis process of practical implementation issue and its applications. The study includes a depth overview of state of-the art back EMF sensing methods, which includes the Terminal Voltage Sensing (TVS), Third Harmonic Voltage Integration (THVI), Terminal Current Sensing, Back-EMF Integration and PWM strategies. The experimental results carried from prototyping platform are given to illustrate the efficiency methods and benefits of the proposed approach and the various stages of implementation of this structure in FPGA.
