Abstract
Back electromotive force EMF is the only electric quantity able to provide instantaneous information on the mechanical variables of the electrical motor; that is true for the position and speed. In this paper, a new sliding mode observer of the trapezoidal back EMF is applied to the BLDCM in order to ensure the control without speed and position sensors. A theoretical study is developed and the results obtained by simulation are presented to show the effectiveness of the method.
