When the switched reluctance motor is running, as the motor phase current increases, the magnetic circuit of the motor will gradually saturate, which affects the estimation of the special position of the motor rotor. Aiming at the above problems, this paper proposes a positionless control method for switched reluctance motors under the condition of magnetic field saturation. Firstly, the Fourier phase inductance function of switched reluctance motor is established, and then the component of Fourier phase inductance function affected by magnetic field saturation is eliminated mathematically. Research the method of estimating the position and angle of the rotor based on the inductance positioning point. This paper takes a 12\8 motor as an example to verify the effectiveness of the method by simulation.

The main purpose of this project is to develop a sensorless control of the switched reluctance motor. As we know the use of switched reluctance has been increasing .Many industries and all other started switching to the switched reluctance motor ,due to there rugged structure and its capability to withstand harsh environments .In this paper we control the switched reluctance motor by controlling the different blocks in the feed back system in the matlab therefore torque controlled .As the switched reluctance motor is widely used in the industry we need to control the switched reluctance motor without using the sensors. Here main aim is to avoid the use of position sensors in the system.
