Abstract: A new scheme to estimate the rotor position at standstill for the sensorless switched reluctance motor drive is presented in this paper. This scheme utilizes the accurate estimation modelling based on the two-dimensional least squares and bisection methods. Furthermore, the optimal sensing phase that is detected via exciting each phase in sequence with a DC voltage for a short duration is used to estimate the mathematical rotor position at standstill. According to the developed logic rules, thus, the physical rotor position at standstill can be determined on the basis of the obtained mathematical rotor position at standstill. The simulation and experimental results validate the presented scheme.
