Line-to-point connection structure and transverse impulse suppression method of flux switching linear motor

Abstract

The invention discloses a line-point connection structure of a magnetic flux switching linear motor and a lateral impulse suppression method provided by the invention. A three-point connection is adopted between the LFSPM motor and the track door to ensure that the secondary stator actively carries the high load of the track door. The synchronous operation of the primary mover and the track door; the use of digital-analog disturbance observers combined with wavelet neural network algorithms to achieve accurate prediction of the lateral impulse at the track door, and the use of reinforced current harmonic injection method for compensation to achieve lateral fixation of the track door and reduce losses . The invention combines a three-point connection structure, a digital-analog disturbance observer, a wavelet neural network algorithm, and a reinforced current harmonic injection method, so that the predicted value of the lateral bearing capacity of the LFSPM motor can quickly and accurately follow the real value, through the three-point connection structure and The optimal control of the mover flux linkage solves the contradiction between loss reduction and control performance, making the LFSPM motor suitable for large-load track door systems.

Description

technical field [0001] The invention relates to a method for applying an LFSPM motor to a large load-bearing track door system, in particular to a line-point connection structure of a magnetic flux switching linear motor and a lateral impulse suppression method. Background technique [0002] Traditional elevator door operators are generally DC or AC rotary motors, so a mechanical transmission device that can convert rotary motion into linear motion must be installed to cooperate with the rotary motor to drive the elevator door leaves. Due to the existence of these intermediate mechanical transmission devices, the transmission efficiency of the system is low, the failure rate increases, and the noise is increased due to wear and tear. Considering that the linear motor can directly drive the elevator door leaf to move in a straight line without an intermediate mechanical transmission device, compared with the traditional elevator door machine based on the rotary motor, the doo...
