Abstract

The invention discloses a PMSM chaotic system rapid terminal sliding mode control method based on a nerve network, comprising steps of establishing a PMSM chaotic system model, initializing a system state and a control parameter, designing a nerve network, approximating the non-linear uncertain item in the system, and designing a rapid terminal sliding mode controller on the basis of the nerve network. The PMSM chaotic system rapid terminal sliding mode control method based on the nerve network can effectively solve the calmness problem of the PMSM chaotic system, improves the rapid convergence performance of the system and realizes the accuracy control of the PMSM chaotic system.

Description

technical field [0001] The invention belongs to the technical field of permanent magnet synchronous motor control, and relates to a neural network-based fast terminal sliding mode control method for a permanent magnet synchronous motor chaotic system, especially for the fast terminal sliding mode of a permanent magnet synchronous motor chaotic system containing uncertain items Control Method. Background technique [0002] Permanent Magnet Synchronous Motor (PMSM) plays an important role in the development of modern industrial production. In recent years, studies by scholars at home and abroad have shown that in some cases, there is chaos in permanent magnet synchronous motors, which leads to intermittent oscillations of torque or speed, unstable control, and irregular electromagnetic noise in the system, which seriously affects The stable work of PMSM is guaranteed. Due to the existence of chaos, the stability of the PMSM control system will be severely damaged, and the tr...
