The start and commutation of the bearingless switched reluctance motor are all through the real-time position detection of the motor rotor, while the traditional position detection relies on the displacement sensor to obtain an accurate position signal, but also brings many drawbacks and shortcomings. The first is to increase the hardware cost and reduce the economy of the system; the vibration of the motor and the vibration of the external environment may cause the sensor to loosen and fall off, reducing the reliability of the system; the harsh working environment such as high dust, high temperature, high humidity will affect the accuracy of the displacement sensor, or even damage it, reducing the environmental adaptability of the system. In order to solve this problem, this paper proposes an optimal control method without a position sensor, and compares it with the existing high-frequency pulse injection method to verify the effectiveness and feasibility of the proposed method.
