Abstract

The invention discloses a linear permanent magnet vernier motor decoupling control method based on improved regression support vector machine generalized inverse. According to an invertibility principle and an Interactor algorithm, invertibility of the controlled linear permanent magnet vernier motor system is proved; input and output of the original system are sampled, after data processing, the data serve as samples for training the improved regression support vector machine, and a generalized inverse system for the improved regression support vector machine approaching the linear permanent magnet vernier motor is used; the improved regression support vector machine generalized inverse is combined with the original nonlinear system to build a pseudo-linear system, and decoupling control on the d-axis current and the primary speed of the linear permanent magnet vernier motor are realized; and on the basis of the pseudo-linear system, a PI controller is added to form a closed loop system, and the robustness of the system is improved.

Description

technical field [0001] The invention relates to the field of linear permanent magnet vernier motors, in particular to a decoupling control method for a novel linear permanent magnet vernier motor, which is suitable for places with high reliability requirements such as rail transit and ship propulsion. Background technique [0002] With the development of urbanization, urban rail transit is undergoing rapid changes, followed by the rise of research on motor traction systems. In recent years, the rail transit system, especially its drive motor, is developing towards a model with lighter weight, smaller volume, faster speed, more stable operation, and safety and reliability. Therefore, it is the key to ensure the reliability of the drive system to be able to stably and reliably control the linear permanent magnet vernier motor that meets this characteristic. [0003] attached figure 1 Shown in is the isometric sectional view of the control object of the present invention. Th...
