Linear modeling method of switch reluctance motor memristor

Abstract

The invention relates to a linear modeling method of a switch reluctance motor memristor. A linear phase inductance characteristic element of a switch reluctance motor is established by adopting an in-phase operational amplifier circuit and an anti-phase operational amplifier circuit; the angular velocity of the switch reluctance motor is integrated by a proportional circuit and an integral circuit to obtain a rotor position angle of the switch reluctance motor memristor to be used as the input of the linear phase inductance characteristic element of the switch reluctance motor; the phase inductance of the switch reluctance motor is obtained in accordance to the output of the established linear phase inductance characteristic element of the switch reluctance motor; a current reversal circuit is connected between the input end of a multiplier and the output end of the multiplier; the output end of the linear phase inductance characteristic element of the switch reluctance motor is connected to the other input end of the multiplier; the input voltage is accessed into the input end of the multiplier; and a relation exists between the output current and the input voltage as well as between the output current and the phase inductance value. According to the linear modeling method disclosed by the invention, the resistance value of the memristor changes along with change of the rotor position. The linear modeling method lays a foundation on establishment of a complete switch reluctance motor circuit and is beneficial to real-time control.

Description

technical field [0001] The invention relates to a modeling method of a switched reluctance motor based on a memristor, which is applicable to switched reluctance motors with various phase numbers. Background technique [0002] The establishment of the switched reluctance motor model directly affects the optimal design of the motor, the static and dynamic performance analysis, and the evaluation of the control strategy. Due to the nonlinear electromagnetic characteristics of switched reluctance motors and the characteristics of multi-variable strong coupling, it is difficult to apply the performance analysis and modeling methods of traditional motors to the modeling of switched reluctance motors. The linear model of the switched reluctance motor highlights the physical nature of the electromagnetic relationship inside the switched reluctance motor, and lays the foundation for the design and analysis of the switched reluctance motor. The linear model of the switched reluctanc...
