Abstract Initial position estimation is the key in sensorless of switched reluctance motor .To realize the start of the switched reluctance motor without reversing, a fault-tolerant initial position estimation method for switched reluctance motor is presented in the paper. Utilizing double current thresholds, the inductance curve is divided into the several regions. At standstill and inertial working conditions, each phase is injected with high frequency pulses, the initial region is estimated by comparing the pulse current with the double current thresholds, the mathematical model of the pulse current and the rotor position is choosed by the initial region, and the initial position angle is estimated. The design of double current thresholds can avoid the initial position estimation error for the pulse current changing slowly at the maximum and minimum inductance region. To increased fault-tolerant function for initial position estimation, a new fault-tolerant initial position estimation method is presented. The experimental results demonstrate the feasibility and the practicality at standstill, inertial working and lacking-phase conditions.

Key words： Switched reluctance motor sensorless initial position estimation double current thresholds fault-tolerant
