Description

technical field [0001] The invention belongs to the field of motor control, and in particular relates to a speed regulating device and method for a switched reluctance motor based on compound fuzzy control. Background technique [0002] Switched reluctance motor is a new type of motor designed with variable reluctance, which has some advantages that other types of motors do not have. The stator and rotor of the switched reluctance motor are designed as a double salient pole structure. There are coil windings on the salient poles of the stator, and the rotor is only a magnetically conductive metal. This design enables the switched reluctance motor to work normally in some extreme environments such as high speed, strong vibration, and high temperature. Compared with the traditional DC motor speed control system and asynchronous motor frequency conversion speed control system, the switched reluctance motor has the advantages of both. The advantage of high controllability of t...
