Abstract

Provided is a switch reluctance motor memory inductor equivalent model. Two second-generation current transmitters AD844-U1 and AD844-U2, two operation amplifiers TL084-U3 and TL084-U4, and a multiplying unit AD633-U5 are used for forming a memory inductor which does not comprise a memristor passive two-terminal element, so that the switch reluctance motor equivalent model is quick in real simulation and control and can reflect the non-linear relationship of magnitude of phase currents and the position angles of a switch reluctance motor flux linkage and a rotor thereof in real time, quick direct mathematical simulation of a switch reluctance motor system can be achieved, important application value is achieved on real-time simulation and real-time control of a switch reluctance motor, and the switch reluctance motor memory inductor equivalent model can be effectively used for real-time simulation and real-time control of the switch reluctance motor. The equivalent model lays a solid foundation for real-time simulation and real-time control of the switch reluctance motor system and has wide application prospect.

Description

technical field [0001] The invention relates to a memristor equivalent model, in particular to a switched reluctance motor memristor equivalent model suitable for switched reluctance motors with various phases. Background technique [0002] Due to the non-sinusoidal winding current of the switched reluctance motor and the existence of nonlinear characteristics such as iron core magnetic circuit saturation, eddy current, and hysteresis effects, it is difficult to establish an accurate nonlinear model of the system. In order to facilitate the construction of the model, the system model is reasonably equivalent and simplified to adopt the equivalent linear mathematical model of the switched reluctance motor, but the magnetic circuit saturation of the switched reluctance motor is ignored and the edge diffusion effect of the magnetic field is not considered. In the accurate nonlinear model of switched reluctance motor, the phase inductance and flux linkage of the motor are not on...
